lan,the only place the letter is with the ser# is on the trigger guard tang and it sure looks like a c. There is a stamp on top between the crossed swords but can,t tell what it is. I forgot to post that there is a crown mark on bbls. The lever is fully engraved and has Westley Richards patent on it. It has high figured wood and the checkering goes all the way around the wrist. Its unlike the pictures in DGJ of the Sherman Bell article about WR.
Thanks! Gordon
