I think I can get a Ruger ramp. I'd swap if you'd like. Let me know what height and I'll see how close I can get.
I agree about the silver blade, I'd probably do a sourdough type blade in steel and brass faced, or red insert like a Smith.
I've looked at original Colt flat top targets, and taken measurments to have sights made, but haven't seen the Uberti version. Would save some time to get one ready made rather than make one. I think Brownells have them though.
