Do you mean OLD French? Here's one from about 1560, found with the lock missing. A job for a client I made the lock from scratch, functional & period-correct. A wheel lock pistol, barrel about 20" long.
Sorry the pix are a bit fuzzy - they are from scans sent me by the owner.
EDIT Couple days later -- Here a couple pix of it before & during -
Of possible interest, I shot over 300 minutes of video making the lock and restoring the rest of the pistol. I would work a few days and mail about 20 minutes video to the client & we would discuss on the phone, then more of the same. Client is arguably the world expert on early European pistols, many books, articles, etc.
