Those gold Bramah’s are amazing, no half measures again lorddlm2! Still haven’t recovered fully from the engraved Hobb’s locks you posted a while back..
Would love to see some of those gold keys, seen some amazing locket and ring variations online but can’t remember seeing one in the metal. What amazed me is the widespread lack of hallmarks on them, as I’m sure you will know our British Hall marking system has always been one of the strictest in the world.
It seems though that there were some more relaxed periods in the past where certain goods were permissible without, or even exempt completely.
It might be worth having a few tests done as most of them that crop up for sale strangely seem to be offered as 15ct which I would have thought an odd alloy in Britain.
Also I vaguely recall the ruling changing and think it now extends further back to about 1920 or so, provided there’s proof of gold content and the age of the item etc. Anyway beautiful key and apologies for rambling on…
oldlock, didn’t you have quite a few of these going back? I recall reading some good posts you’d made on here regarding the different gold versions.
