Unusual Bramah lock on a satchel / document case

So just picked this very unusual item up.
Leather satchel type case with a fairly large Bramah lock and steel bow key on the front

Has anybody ever seen the like ?

Please advise if you can date it. it just says BRAMAH
No numbers or letters at all.

I will try to work out posting images if of interest.

Now that is really cool case you got there. Just maybe the number or letter could be on the other side of the lock or inside of lock…Timothy…..

Almost certainly not genuine Bramah as there is no full name or address stamping.

It’s an example of a ‘Banjo hasp - Folio Lock’
