Uberti, has a model like that right down to the stamp on the wood grips. I checked Cimmaron and EMF and while they used to offer those, I don't see them now on their web site. You may well run across them used, and you could also check Gunbroker. I see there is a pair of real Colt 2nd gen guns there with consecutive serial numbers, unturned (of course if they were mine, I would shoot them!) if you want to spend the $$$$. You should at least see them. Put in 'cavalry 45' and they will come up. Hope you can find something that will work for you. 44 Man
