I have a cute little sidelock SxS 410 marked Crescent-Davis. As far as I know, this was put on guns made by Savage in the early '30s. Apparently, Crescent guns were made by Folsom(?), who was swallowed up by Savage around 1930. There is a Davis-Warner in there someplace, too. Does anyone out there have a good reference for Savage and/or Crescent? Thanks!
