About 3 years ago I sold a Finn M28. Perfect stock (probably a replacement) but the action and barrel had a lot of "patina", and had, as I remember, three different SNs, two of which were lined out. It had the Civil Guard "SY" stamp on the front receiver ring. It also had a Hammerli barrel. A guy drove all the way from Houston to buy it, and he was really happy to get it. He didn't even attempt to bargain. I think I got $400 for it, but I don't remember the exact price.
