Don, you are right, as I can remember now the price in the late 60's was closer to $275.00, not $375.00. I think that price it what a friend of mine payed for his 20 ga. Browning Superposed back then.
The serial number on my Winchester 101 20 ga. is 2046xx.
It is kind of semi-retired, but I think I will have to take it out for a breath of fresh air.
