Well the same way I found my .327 FM Ruger SP101 3 inch model. Browsing this evening & bingo this Ruger Blackhawk Convertible Model pops up the seller possibly wants to trade. Well I sent him a text asking him what is he looking for. So we will see, now my question's are just a ball park figure how old might this gun be? From the pictures it appears to be in really nice condition. Yes there are 2 cylinders with this gun. Ever since I acquired my .327FM SP101 wow this .327 is a neat ctg. giving more ctg's to fire in the same gun! I would greatly appreciate any comments on features & possible rough value on this Blackhawk Convertible where it's a Blackhawk I am assuming its a larger framed gun vs the current Ruger Single Sevens now being made. I know at one time Ruger made a 8 shot Blackhawk in .327FM so would this Convertible .32H&R/.32-20 be on this same frame size?? But again comments much appreciated thanks!!!
