I've owned a number of them and they are great revolvers. The DWs built in Monson, MA are the best of the bunch. Quality and strength wise, they rank right up there with S&W, Colt, and Ruger.
DW didn't really use model numbers like the other manufacturers - they did make some with numbers though. CZ-USA owns DW and still supports the revolvers and extra barrels, shrouds, and other parts are available...
