" As an example a 16 gauge model 21 Winchester will bring more $$ than a 12, all other aspects being equal."

The reason is that more 12's were built than 16's and the Model 21 is a collectors game for the most part.

Post war M37 16 barrels are significantly heavier than pre war barrels.

I have ordered three bespoke 16's, A 6# 0.1 oz Bruchet/Darne, 5# 9 oz CSMC Fox and an AyA #2 which I never actually took delivery as they built the wrong frame.
They were ordered just because. They could have just as easily been 20's.

There is no doubt that the 16 has gained in popularity in the last decade or so, you just have to seperate out the $$ valuation due to collectability from the actual popularity.-Dick
