Only number 1 on locks. Here is the initials barrel knitter. KA?
Gun weighs 5.6lbs 29” barrels and looks like original lop was 13” has widows peak so doubt was shortened. Almost child or women’s size gun, super diminutive frame also. Guess my 12 year old hit the jackpot! Barrels are approximately .110 thick at front of chambers and .040 thick at 2/3s down. They will get honed pretty rough but no visible deep pits. I have never feared Krupp fluid steel barrels that measured this reasonable. Only needs 3/4-7/8oz loads at this weight anyway.
