·Thought I'd share a few things I know about the 28-1 for you gents. And 4-Screw Dash Ones in general....much of what follows is gleaned from emails that Bill Cross and I exchanged. For those that do not know Bill, he is both a extremely knowledgeable collector and a fine gentleman. So much of what follows should be credited to him....
Few general rules from over the years, the -1 model variation would best be described as a 4-screw frame, extractor rod with a left-hand thread as evidenced by a small relief cut behind the knurled tip, "L" stamped on the rear surface of the cylinder, stamped MOD.XX-1 in the yoke cut.
We are only talking about models of revolvers that were stamped -1 when the extractor rod threads were changed from right-hand to left-hand as directed by the engineering change dated December 22, 1959.
The engineering change to implement the extractor rod with the left-hand thread was issued by S&W on December 22, 1959 and resulted in revolvers with the -1 model variation. The engineering change to implement the improved cylinder stop with the elimination of the cylinder stop plunger screw was issued on November 28, 1961 and resulted in revolvers with the -2 model variation. The time it took to implement these changes was substantial as the -1 models were shipped throughout 1962 and the -2 models began in late 1962. Remember, the SCS&W is a general guide and only that.
The change to the extractor rod with a left-hand thread was authorized in late 1959, but -1 models did not begin to be shipped until 1962 and most were shipped in that year with a few carrying over to 1963. The -2 models also appeared in late 1962, so the the -1s were really only shipped for a year plus.
The engineering directive to implement the improved cylinder stop that resulted in the elimination of the cylinder stop plunger screw (i.e. 4-screw frame to 3-screw frame) was issued on November 28, 1961 and was implemented much more quickly as revolvers with a 3-screw frame began to be shipped in early 1962.
Bill Cross believes and has demonstrated that the Model 29-1s can have a 3-screw frame. He also has stated that S&W had old style extractor rods and cylinders, but had made the switch to the 3-screw frame and used up the old cylinders and extractor rods on the "new" frames. Not sure why these guns were actually stamped MOD. 29-1 in the yoke cut, but they were.
Thanks to Bill for much of the above...Hopefully he'll be along to straighten anything I may have inadvertantly "screwed-up"
