... I do not see how an Airweight Chief could have a serial number in the 1XXX range. Would not that be a 1951 serial number? As I understand it, the Airweight was not introduced until 1953. I too will be interested to see the pictures.
According to Roy Jinks' book,
History of Smith & Wesson, "The Chiefs Special Airweight was introduced on September 12, 1952, with the first revolver bearing serial number 1,785...."
Roy doesn't say whether the first ones were made on the Baby Chiefs frame with five screws or, like the ones in the 27XXX through 29XXX range, were 4-screw "Model of 1953" Chiefs.
Additionally, Supica and Nahas in their
Standard Catalog of Smith & Wesson, 4th Edition, say the Airweight was introduced in 1951 with a 5-screw frame, but those seem to have been assigned "X" (experimental?) serial numbers, and they were "quickly changed to 4 screw for 1st production run."
Trying to tie all this together, "wiskerchew" could have found one from that first run. Hope he'll come back and let us know with photos.
Roy does note (not related to Airweight models) in the Chiefs Special database under this forum's "Downloads," that Chiefs Special serial number 225 had an "over-size trigger guard," and that gun shipped on "September 4, 1951."
This all leads me to question the "Model of 1953" designator, because it seems there's a chance the longer trigger guard, at least, might have been on the street as early as 1951. Of course, I have found no mention of the grip handle length getting longer till the Airweight models of 1953.
