Daryl, good question. I know L.C. Smith used most that had their name on them, plus they also used a few that did not. I posted on the LCSCA about an early Fulton 2E (circa 1896) that had a butt plate with two pointing dogs on it and said I have seen a few "elsies" with this same butt plate. A viewer wrote in and said that this butt plate was used by a few other gun manufactures and not just L.C. Smith. I agreed since it does not have any name on it and therefore could be used by anyone. I believe all of the gun manufactures had them made elsewhere and don't believe there was many to begin with.
It would be nice to find an old catalog of such butt plates and grip caps and who made them.
