The sense I get is that American classic smallbores still move pretty well at reasonable prices. When you look at what's available, you see lots of 12's--which is understandable since far more 12's were made. I think it's even truer with Brit doubles, where there's an even greater spread between 12's made vs smallbores.
The smaller gauges move well. LGS had PA A.H. Fox 'Sterlingworth' 16ga with medium weight barrels with Whiteline recoil pad and poorly installed single non-selective trigger of origin not known to me. I passed on the gun because the inertia trigger did not work right. It sold quickly despite $1400 price tag. They also had 16ga West German Sauer, pre-WWII 16ga Simson, German Merkel 147 20ga. All sold in reasonable time and not for give away prices. The 12ga offerings seem to linger on.
