I came across a Mossberg 600CT (New Haven) in 20ga in absolutely MINT condition. I think it's from the late 70s. It's got a fixed adjustable choke on the end of a 28" VR barrel. The guy wants $150 for it, which I'd probably pay for anything that fires. Am I getting a steal here or is that all it's worth? I'll probably make it a turkey gun if it shoots well.
