The Bayswater's Place in the Market
Mulberry introduced the Bayswater in 2003, and it quickly became the defining British It-bag of the decade — a structured shoulder bag with the distinctive postman's lock closure that references English postal history. The Bayswater is positioned below Chanel and Louis Vuitton in price (typically £800–£1,200 retail) but occupies a specific aspirational position in the British market that drives a consistent fake trade. Because the lock and the tree-logo padlock are the two hardware pieces every Bayswater carries regardless of leather or colourway, they carry more of the authentication weight here than on brands where hardware varies model to model.
The Postman's Lock
The postman's lock is the Bayswater's most distinctive element and the most scrutinized authentication point.
Mechanism: The lock clicks open with a specific pressure applied to the lower face — a satisfying, confident click with a definitive release. It closes with the same firm click. Fakes often have loose, imprecise mechanisms that require force, rattle, or don't click cleanly.
Weight: The lock is solid brass — it should feel heavy. Lift the lock by pinching it — it should have a substantial, cool weight. Lightweight or warm-to-touch locks are not brass.
Finish: Authentic locks come in gold or silver finish. The finish is consistent across the lock face — no patchiness, no areas of rubbed-through plating on a new bag.
Engraving: A small tree logo is struck into the lock face, and the surrounding plate is stamped with the flat-head screws that secure it in place. The engraving is deep and clean — legible without a loupe, with crisp, non-mushy edges to the tree's leaves.
Screws: Genuine Bayswater locks are secured with flat-head screws, neatly aligned and sitting flush with the plate. Cross-head screws, or screws that sit proud or crooked, are a documented fake indicator.
Front plate proportions: The postman's lock has a specific width-to-height ratio. The lower bar (the part you press to release) is a specific width relative to the upper plate. Fakes frequently get this proportion slightly wrong.
Worth knowing
Photographed side by side, a well-made fake lock and a genuine one can look nearly identical — engraving depth and screw type are the two details worth checking closely, but neither is reliably visible in a typical listing photo. This check rewards handling the bag far more than it rewards a photo.
Leather Quality
The Bayswater is produced in several Mulberry leather types — Natural Leather (the heritage option), Smooth Leather, Soft Grain, and others.
Natural Leather: Mulberry's heritage vegetable-tanned leather. It starts as a firm, dense leather and develops a rich patina with use. On a new Natural Leather Bayswater, the leather is relatively stiff. Fakes sometimes use softer leather and market it as Natural Leather — the stiffness of new authentic Natural Leather is a tell.
Smooth Leather: Polished, supple calfskin. Authentic smooth leather is consistent in sheen and soft to touch. The surface shows fine natural grain under close inspection.
Soft Grain: A grained calfskin with a specific pebble. Authentic Soft Grain pebbles are fine and consistent — not coarse or wildly irregular.
Touch test: All Mulberry leathers should feel cool to touch. Synthetic alternatives warm up quickly.
Worth knowing
Leather feel and stiffness are genuinely useful but entirely dependent on handling the bag in person — they cannot be assessed from a listing photo, so weigh this check accordingly when buying remotely.
Interior Stamp
Inside the Bayswater, a gold-foil or blind-embossed stamp reads:
"MULBERRY" (top line)
"Made in England" (second line)
Below these, the serial number appears on some models.
"Made in England": Mulberry's heritage production is in Somerset, England. Authentic Bayswater bags have been "Made in England" since the brand's founding. Some Mulberry products are made in other countries — but the Bayswater specifically should say "Made in England."
Note on production shifts: Mulberry has at various times moved some production outside England. Verify for your specific era — some later-production Bayswaters may have different origin stamps. For primary authentication, "Made in England" remains the expected standard for bags marketed as the heritage Bayswater.
Font: The interior stamp uses Mulberry's specific font. The "M" in "MULBERRY" has specific proportions — its center V dips to a particular depth. Any deviation from the documented font is a tell.
Hardware Consistency
The Bayswater has additional hardware beyond the postman's lock — D-rings for strap attachment, the turn-screw closures at the base corners (on some versions), the shoulder strap hardware, and the small brass padlock-and-tree-tag charm that hangs from the front strap loop on many production years.
All same tone: All hardware on a single authentic Bayswater is the same tone — gold or silver, not mixed.
D-rings: Heavy cast metal, consistent with the lock's weight.
Strap hardware: The shoulder strap (if included) has hardware that matches the bag.
Padlock and tab: Where fitted, the small brass padlock and its leather tab are worth close attention — genuine hardware is highly polished with a crisply struck tree logo, and the tab is tightly and evenly stitched into the loop it hangs from.
Red flag
A padlock charm cast in dull, low-reflectivity brass with a shallow or blurred tree stamp, paired with loose or uneven stitching on its leather tab, is one of the more consistent tells across the fakes reviewed for this guide — genuine hardware is finished to a noticeably higher standard.
Stitching
Thread: Mulberry uses thread that matches the leather — not a high-contrast thread on a natural leather bag, for example.
Stitch count: Even and consistent across all panels and handle seams.
Handle attachment: Where the handles attach to the bag body, the leather panels overlap in a specific construction and are stitched through multiple layers. The attachment should be secure and the stitching clean.
Handles
The Bayswater's rolled top handles are a signature element.
Roll construction: The handles are rolled from a single piece of leather over a core — they should feel cylindrical and firm, not flat.
Handle leather quality: Same leather quality as the body — same color, same texture.
Handle drop: Authenticate the handle drop length against documented specifications for your specific Bayswater size.
Sizing
Standard Bayswater dimensions: approximately 38 × 29 × 16 cm. A Classic Bayswater Tote is slightly larger. Verify dimensions match what's stated.

FAQ
Is the Mulberry Bayswater always made in England?
Mulberry's heritage production is in Somerset, England. The Bayswater is primarily a "Made in England" bag. Some Mulberry products are manufactured in Turkey or other countries — but the classic Bayswater should be English-made. Verify the interior stamp for your specific bag.
What leathers does the Mulberry Bayswater come in?
The Bayswater is produced in Natural Leather (the heritage option, develops patina), Smooth Leather (polished calfskin), Soft Grain (pebbled calfskin), and seasonal special materials. Natural Leather Bayswaters are the most heritage option and typically command higher resale values.
Does the Mulberry Bayswater come with a serial number?
Some Bayswater versions include a serial number on the interior stamp area. This serial can be verified with Mulberry for authentication (Mulberry offers verification services through their boutiques and online).
What's the most reliable fake tell on a Mulberry Bayswater?
The postman's lock mechanism — specifically the click and the brass weight. Fakes use lighter, less precise locks. Any lock that rattles, requires force to operate, or feels light relative to its visual size is not authentic. This can be assessed immediately without specialist knowledge.
Why is the postman's lock significant to Mulberry?
The postman's lock is a direct reference to the traditional locks used on English postal bags — consistent with Mulberry's English heritage positioning. It was chosen by founder Roger Saul as a functional closure that also tied the bag to English craft tradition. The lock's quality is a statement of brand identity, which is why fakers consistently get it wrong.
