I have a set of 1851 Navys that I rebuilt last year, fig navy 36 cal revolver italy xxiv made in 1968 that is apart in the pic. The other is a 1851 44 cal revolver italy xx8 made in 1972. I bought all the replacement parts off of ebay. That said You may have to mill them or fill them down to fit them to your make. But they are ez to rebuild.
