My dad was a gunsmith and did it more for the pleasure than for the $$
He would not allow me to have a BB gun as a kid, claimed they just taught bad habits as a result of most not believeing that they were "really" dangerous. Not sayin that he was right, just sayin it was his belief.
Winchester .22 pump with an octagon barrel at 10 yrs old. Lost it to a thief in the early 70's along with the rest of our firearm except for a Mossberg 500 I bought with paper route $$ from Herters in 1965. It was at my uncles home when the other guns were stolen. Oh, and dad had a 1/2 dozen surplus mauser actions stored in the attic for later builds, that they did not find.
That was over 35 yrs ago and I'm still p. o. about it!
