Thanks very much for the great help, you guys really know your stuff.
I have the Sauer with me now, it is in really fantastic shape. I think the date is 1953.
I don't think I will shoot it much, it is very very light and does not fit me well at all. This is what I get for impulse buying like I did. It really is a beautiful piece though. Somebody did not use it much and kept it up nicely.
Already have buyers remorse, a real decent Browning Superposed 20ga just came available and I could have bought that as ive wanted one forever. Shame on me
