Another thing I’ve noticed is there is a gold colored inlay in the super grade letters on the floor plate, don’t know if that means anything, I’ve seen that added by individuals on colt single actions in the past so I assume it could be on this as well. I’ve honestly never handled a super grade from that time, I have a couple but they are both the recent maple production. I would post some pictures but my internet connection isn’t great here and I haven’t been able to figure it out yet. Really wanting to get something figured out on this if o can because I’m thinking about selling it. I have 2 other 300 win mags I favor over this one and where and the way I hunt I really don’t need another, thinking this could fund another gun purchase, I just don’t want to let go of something special too cheap or at all if I found out something interesting about it.
