I think I just found out how much factory ivory grips are worth. Gunbroker had a demilled Single Six in the 103,000 serial number range that had FACTORY IVORY GRIPS with it. The Single Six and the grips sold for $2,125 about 9:15 PM tonight. I was the underbidder. I bid more than I told myself I would, but I still didn't make it. RENE states they should be worth about $2,225; seems that is correct!
