Francotte Experts Out There?

Neither the action nor barrel flats have a date code.
A 1955 gun would have this Smokeless Proof mark



and the bore and chamber length within a lying Omega; a 1937 gun with a 'p' date code



I have been a bit confused by the bore over muzzle constriction mark, not usually found prior to 1910, which suggests the gun may have been reproved at some point.

Very similar barrel markings on this Von Lengerke & Detmold import which by the SN would be an 1899 DOM

Drew, my main point for posting this was because (exactly as you indicated), it did not have the smokeless proof and it also does not display the chamber (70MM). Your point about the date code also makes sense. This gun screams modern and custom to me.
