Very good info.
As has been stated by me previously, I collect Italian (Pietta) replicas.
Pietta makes a Dance .44 based on a lowered Navy .36 frame and a smooth non-rebated cylinder that is larger in diameter than the .36 cylinder, which makes it not historically accurate, nor parts interchangeable among other Pietta 1851 Navy pistols. I have been urging Pietta (via emails) to make a Dance .36 on a 1851 Navy frame for a couple of years. All Piettas these days are CNC machined, and it would be very simple to mill off the recoils shields before doing the case colors and using the part octagon/part round barrel from their G&G .36, instead of all of the changes they had to do in producing the Dance .44.
I guess it all fell on deaf ears.
Pardon my rambling.
