My post did indeed include all the Kerrs on the Pratt Role...there are a few other English revolvers, but that's all the Kerrs listed...Coompany H of the 18th Virginia Cavallry was a small company by the summer of 1864.
The frame marking in confusing - it gives notice of two things - first, that this is a Kerr's Patent revolver, and second that this is Serial No. 9522. Colt marked the cylinders of his percuission revolvers the same way - the cylinders of Colts percussion revolvers are marked COLTS PATENT No. [Serial number]
