I have a fair amount of parts for Colt Signature Series BP revolvers. Yes, Pettifogger is right, ( Hi Larsen) Uberti made so they are good to go there also. I don't have every part. Some models just a couple. The parts vary, some are "new in the white", some are "nice & new", some are new & have a few marks from rubbing around next to other parts, some have cosmetic flaws & some are used in varying amounts.
I do not have a price list as there are 100s' of parts & as in 1851 Navy barrels, at least 4 grades to price. Next thing is if you just need one part it still has to get shipped. It's a much better deal on the shipping if you want multiple parts. Best is to just shoot me a list with the models & parts you want & I'll see what I can do to help. I do not have any hands for any model.
If you are lookin' for spares or parts to peronalize or customize drop me a line. (cool note, barrels don't have them BP warnings)
