I've just acquired (from the Auction Site of the Beast) a "Bramah box lock". I'm wondering if it's genuine. Compared to other Bramah locks I have, both old and brand new, it just looks "wrong".
It's an unplated brass finish, a box lock. The strike plate has loops (a Bramah feature) rather than the more easily forced open hooks on most other box locks. The top plate is stamped "BRAMAH" and "SECURE". I've seen other Bramahs on '20s / '30s jewellery boxes that were marked in this style rather than the script Bramah signature, but they had "BRAMAH" and "LONDON" - I've not seen "SECURE" before.
The key is 5mm in diameter and has four unevenly spaced levers. Right for a simpler box lock. The nozzle is conical brass, with a slight cove to the surface and milled rings.
Internally though, it looks crude. The casting surface is rough, then snail cam on the bolt appears to have been cut with a knife and fork. It just doesn't have the quality feel that other Bramahs have had. Action is OK, but feels a little stiff with age.
Any thoughts ? Can anyone suggest a reference for age variations to Bramah locks ?
