As a postscript to me earlier post, Don obliquely hit on a couple of interesting points about the 21.
When the 21 came out the other double makers were mostly belly up and gasping for air. Incredibly, Winchester sold a realtive ton of 21s in the thrities, depression be damned. Evidently people were impressed.
Trapshooters may be the pickiest of the lot, and a good number of well known trapshooters cashed out their Parker/Smith/whatever in favor of the new 21.
Ultimately, the M21's place in history was secured when Winchester decided to keep the 21 in production on a semi-custom basis, and then on a custom-only basis long after the profitiability had faded into memory.
