I just visited Carl Walker, who worked at the Green River Rifle Works. He is sawing out two Kit Carson stocks for me from blanks. He showed me a .54 Leman he just completed for the GRRW Collector's Association, Serial Number L-1. He browned it with Track's Tried and True Brown, which looked like the brown on my GRRW Leman I built in their shop in 1978, but had them brown. (He has the recipe for GRRW Browning Agent, but says it has some nasty stuff in it, something mercury, so he doesn't make his own). He said he browned it in 48 hours in his unheated basement, with a humidifier in the room. He said he much prefers this T&TB to Laurel Mountain Forge Browner and Degreaser, in fact he gave me his bottle of that. Just another option for browning.
