Thanks for the information. Once I obtain a copy of the ad I'm sure that will go a long way towards authenticating the revolvers history.
After comparision of the engraved name on the backstrap with with other 19th century script I believe it to read T.W.Richards. Whether the name was on the revolver when Proudfit obtained it, or was placed there by its Confederate user remains to be seen. Their are several possiblities listed in the NARA Civil War database.
