My friend had one like this... https://www.buckknives.com/product/183-blackout-crosslock-knife/0183BKS-B/
Without more info on the particular knife he described its tough to say what he had. I think vintage Bucks are awesome, the 317 is a large 2 blade folder or the 380 is a smaller more trapper like folder. Buck made a Selector in a 2 blade model. the 428 i think or similar. All of the above are available on Ebay. Several in mint condition. Probably in your price range. Not trying to discourage from a new blade. As 150 will likely buy alot more knife now. But something about gutting a buck with an old knife is just plain cool to me.
AL Mar, makes a really nice blade.
