Thanks and interesting.
Here is another 1930 demi-bloc FNhttps://www.gunsinternational.com/g...lbs--4-oz---tough-g.cfm?gun_id=101114544
Chantry's gun does have 2 3/4" chambers
' is the 1930 lettre annale
The barrels at the time of proof weighed 1.371 Kg = 3.02 #. If > 3% less now (from honing) the barrels are considered out of proof
NORIS was a brandname used by Wilhelm Meyer Waffen in Nürnberg, established in 1920, and possibly still in business. Maybe Meyer supplied the gun to Leopold Bieder? Acier special
was the barrel steel tradename used by FN. "Special Steel" by Browning. Supplied by Cockerill.
The interesting part
After 1924 the muzzle measurement was not marked; just 'CHOKE' if > .08"
The tubes at the time of proof were 18.3 mm = .720"
They may have been honed at the time of reblacking and marked 18.4 = .724"
The arrow indicates what appears to be a 'phi
' in the box, which is the lettre annale
for 1961. It is likely that the gun was reproved then, in Belgium
, not Germany.
What is the bore now, and what is the weight of the barrels?
Fun everything that can be learned from the Belgian marks. Neat gun
