Greetings, New to the forum! Picked up a first year A5 a week ago for less than $100. Have broke her down and photographed what I have. Saw that there was some interest on documenting early A5s so thought I would share. Very early serial number. She has a broken rail on the locking block and the breech block is damaged as well. I will post photos of the internals if there is interest.
With my limited knowledge that makes your gun a 1920's model! Amazing find and well done for picking her up and bringing this classic back. Lovely gun thanks for sharing.
Congratulations on your first year Auto-5. Too bad about the Locking Block, as far as I know those early parts are unavailable. But, since the first guns had rails on both sides of the block, and later guns only one, I'd bet it's still safe to shoot the occasional target load.
What is interesting is it appears just the trigger was replaced, the housing is serial numbered to the gun.
Fore stock has the finger groove all the way through. Although this is an early one (started this type in 1909) it is not correct for a first year gun. Should have a finger stop.
