the serial numbers are 90338 on every main part. and only on the hinge does it read the numbers "00" and the patent dates. On the barrle it reads "Hunter Arms CO. Fulton N.Y" and "Armoured Steel". it looked to me like all this pointed to a pre-1913 model. But the serials showed otherwise.
Writing it all has suddenly made me very confused about the exact date of my gun.
