I'd pay $150, partly because I like finding a good deal, but mostly because you don't know what is it. Get some pics of the receiver ring and someone here can identify it. I like the Czech mausers personally, but my uncle has a m96 swede that will absolutely shoot the lights out! Any mauser is a good mauser(for the most part). Show us what your looking at, you've got me excited now.
