One other thing to be aware of when contemplating using a salvaged SAC stock on another SAC gun; in 1902 SAC widened and lengthened the top strap, and also extended frame sides so that the sides of the stock could be inletted into the frame (as with an Ithaca Flues). This means that stocks made after this production transition will not interchange with/fit frames on earlier models and vice/versa. Also be aware that SAC used at least three different sized 12-bore frames, which could also impact interchangeability within stocks from the same production period.
