That would mean he needs a buttstock for the FW frame series- Does he want an original 1913 stock- possibly from a "parts gun" or a later stock blank he can fit-

Re-stocking L.C. Smiths, as well as other sidelock shotguns, is a job calling for a top-rate stocker, not a job for an "rookie" with a few chisels on the bench. I very seldom if ever get buttstocks or forearms for not only Smiths, but other American doubles as well. Good luck!!
