Three die set in a RCBS green plastic box. I acquired these with a used Dillon press and I have never used them. I bought the press from the son who told me his father had reloaded up to a few weeks before he passed. There is no visible rust or damage but there are a few minor wrench scuffs. The sizing de-cap die is stamped "RCBS .45 colt carbo FL s" the seating die is stamped "RCBS .45 colt seat". The third die appears to be for belling the mouth of the cartridge and is stamped 45 colt also.
I don't know much about .45 colt and I will entertain a cash offer or a trade of some sort.
