Just a couple of comments here. Without even getting into the debates over the M21 itself, keeep in mind that high prices do not necessarily imply aany special significance to the actual value of one product over that of another. Prices on items no longer in production are driven simply by Supply & Demand. There are ""MANY"" Winchester collectors, thus Demand. That is a definite factor in their prices. I recall the statement made many times by the late Russs Rupel "Only a Collector will pay more than something is Worth".
As to bbl construction I have the following list, anyone feel free to add any I may miss;
Conventional
Dovetail
Chopperlump
Dovetail Chopperlump
Shoe
Monoblock
Not absolutely positive but I believe that a Demi-Block is another designation for a Chopperlukmp
The Winchester 21 bbls are the Dovetail Chopperlump
