I tend to enjoy the No.1 for what it is, pretty flexible as to caliber, cosmetics and has a little class to it. I could care less about their value, how many they made etc........I just like them...........
I shoot a long gun left handed, a left master eye comes into play for me. The factory No.1 has no extras to speak of in the buttstock, such as cheekpiece etc and seems fairly straight to me. Never worried about such, seems to work ok for me; do wish the length of pull was a bit longer; hence my needs for new stocks on occasion.
Of course, the furniture can be replaced with a stock attuned for your own tastes, dimensional as well as cosmetics, such as cheekpieces, etc etc. I sugguest if you never shouldered one to get an idea of relative fit, there are some around for trial I am sure in the various spots.
Some will relieve the side of the action a bit for ease for lefties, but I have never done it myself. Seems to lend itself during loading ok as is, for my needs.
