Thanks guys! No progress this weekend, too damn cold. The pistol is a US Revolver Co. .32 cal solid frame. Made by Iver Johnsons Arms and Cycle works between 1911-1935. They were 2nd line guns made to use up old, left over black powder parts, sold by mail order and never listed in the IJ catologue. By most accounts, a decent shooter, but not much collecter value. about $50-100 depending on condition.
