DWs were originally made in Monson MA, then Palmer MA, and finally in Norwich NY.
Of them, the Monson guns are still consistently the best. Some Palmer guns are fine - though not up to the best of the Monsons - and some are sub-Rossi quality. If looking at a Palmer gun, one needs to check it thoroughly for defects.
The Norwich examples, gunwriter hype notwithstanding, are roughly on a par with the better Palmers; they still aren't as well constructed as a good Monson specimen. I've actually had to send brand new Model 715s back to Norwich because of severe fitting issues; the replacements weren't much better.
Just MHO, of course, but I see more DWs than most do.
