Looks great from the door shots- is the lower (bottom) locking bolt chamfered with a latch action?

That was a nice feature found on certain Bauche and Fichet models, yet another one that British makers never adopted!

In a commercial environment it's actually a very useful feature to have. Fichet-Bauche continued it on certain models- even on relatively big cash safes like the Chatel and Enterprise until at least the late 1980's.
extremely useful in busy cash handling offices where the safe is constantly being accessed and the full 'lock up' isn't needed until close of day.

Often wondered who came up with the idea first!
