When did they close out those guns? Looks to me like you'd get something less than 3x your money for a 28ga today vs closeout price. Maybe closer to 2 1/2x, which is still quite good.

I bought a BSS Sporter 20ga, new, in 1980 for $400. That one, I'm sure, would get me at least 3x my money today. Maybe pushing 4x.
