The first Number 1 I bought (in 1971) was a 1-A in 30/06 and it was a great rifle. At that time, they were hard to come by and another fellow wanted it even more than I did so we did a trade in which he gave me a new 1-B and some boot. It took about a week for me to really regret that trade. I soon realized that I carried a rifle a lot more than I shot it and that 1-a carried very well. GD
