What I got from Dixie gun works were origional peabody rim fire breech blocks and firing pins. These still have to be converted to center fire. At one time Dixie did have Romanian center fire breech blocks and firing pins. But they sold out quite some time ago. I have a gunsmith who will do the conversion on my peabodyI do not have the necessary tools to do it on my own. Since he can get the proper reamers (50-70) I'll be sending him the brass, bullets and dies as well. I could get this rebarreled to 45-70 if I felt so inclined. Probably would be cheaper in the long run. Everything for 45-70 I have except for some cast bullets. Plenty of places one can get a nice trapdoor bbl. Forend wood and barrel band might pose a problem though. Would only run trapdoor loads through it. As far as going to the 50-70 well since i'm going to end up cutting down 50-70 brass to get the correct length cases I might as well go whole hog and get it rechambered to 50-70 and some trapdoor sights thrown in for good measure. Should be a thumper. Cast bullet molds start at about 330 grains and end up at about 500 + grains. Those 50-70 cases are over a buck apiece. The 45-70 cases I have cost about less than 25 cents a pop. Another plus for the 45-70 Frank.
