I still have the Marlin bolt action .22 rifle with a tubular magazine my Dad bought for me in 1957 when I was 11. No serial #.
An 11 year old with a .22? Folks would faint dead-away seeing such a thing, today. I used to walk towards the woods (and my elementary school) with a .22. Put the bolt in my pocket. I remember a cop driving by. No problem. Early ‘70s.
