Bisley grip frame on the bottom one?
looks like a modified Super Blackhawk grip frame to me, it has the squared trigger guard
But the grips are rounded and the frame looks to be stainless (could be the lighting)
I might have figured you two would notice the difference.........

It is a Super Blackhawk (all of them are).
I call it my hybrid grip frame......a cross between stock and a Bisley.........

The frame looks like stainless but it is the factory blued steel frame. It is silver now from the reshaping and polishing work I did to it a few years back. I have not messed with it in a while though (lazy I guess). When I'm done with the metal work I'll re-blue it. I've always been a sucker for the blued steel guns.
Next I want to reshape the trigger guard to a rounded one. I love the gun but hate those squared trigger guards (what was Ruger thinking?)
I've slicked up the factory guts, (it's a heck of a shooter) but now I have considered starting over with one of those kits to give it the extra click when cocking, and free spinning cylinder for loading. I'm also thinking of going to a 5 1/2 ' barrel.
It is an ongoing work in progress so please don't judge it by the grip panels that are on there now (ugly as a train wreck, but they do feel good in the hand). They are temporary until I can find some nice curly maple.
