Product
Born July 21, 1813 Ón Juaniata Country, Pennsylvania, moved to Tiffin in the 1830s.

See Gross Arms Co. and Cosmopolitan Arms Co.

Carbines sold by Cosmopolitan Arms Co. and those of Gwyn & Campbell, both in additional often marked and refered to as Union are quite identical but there are some differences. Especially the lever.

The Cosmopolitan's guns were based on the patent of Henry Gross (see Gross Henry). Edward Gwyn requested for an English patent for identical mechanism which was granted on December 20, 1859 (English patent had the number 1489). Campbell brought the funds. Today it seems that both has to be to consider as separate manufacturing. Sorry when still melting information. I am not yet certain which was made by whome. It is not of help that in historic records both guns were often named as Union Carbines.
