Thanks for the replies. Sorry it took so long for me to get back, been away.
I did a little research on the net and found that the crest on at least 2 are Brazilian Mausers (based on the crest)---the model 1908's. But they say Germany, so that is kinda weird, I guess Germany was making them for them. Anyhow, I don't have a camera to take pics of them right now. Any idea how I can find out what caliber they are? Would a gunshop be able to tell, or would I have to take them to a gunsmith? They are in VERY good shape, like new in fact. I'm curious as to what they might be worth. I'm thinking they have to be worth $400 each....or am I way off base? They all have scopes (cheap but new), slings and cases.
They are cool guns no doubt. I think I'll keep one and sell 2 most likely....once I get all that figured out.

Also, they are all 3 sporterized. I know that doesn't really add value, but they are nice. They really all look like new.
Are there any websites that I might be able to find out how much they might be worth....based on what they are? Or do you think I might have to deal with a gunshop/gunsmith for all of that?

Thanks!
