Slowhand,
Agreed! That is a very interesting era in firearms development. I have some examples of early Harrington & Richardsons (made after the Wesson & Harrington partnership) that I feel are interesting. Included are the AEtna and Victor "off-brands" made by H&R in the 1870s into the 1880s.
Heres's a couple pics to show some of the variety.
