I have owned an M-43 Spanish Mauser for many years. The bolt matches the receiver as do the other parts, however the safety is mismatched. The bore shows very sharp rifling, but is dark. I see no rust. It is in very good condition, but certainly not pristine. Date is 1947.

I have never fired it, but am interested in doing so as soon as it cools down in AZ.

Question: is it safe to fire with surplus military ammunition? Any ideas as to value?

Thanks for any information you may be able to provide.
