Does anybody know if the humble Model 37 Winchester single shot shotgun was made with one, two, or three frame sizes? I only have my original 1951 .410, but had a 16 once and seem to remember that it had a larger frame. True? And was that larger frame shared by the 12 and 16, or was there an even larger one for the 12 guage? And if there were several different frame sizes, which ones did the 28 and the 20 use?
Winchester made more 37s than any other shotgun, but since they don't seem "collectible," there isn't a lot of technical information about them around.
A personal observation: for cheap guns, they pattern, point, and function very well!
