I did a check for
38 colt spl. and did not find anything
Without some chamber and bore dia. numbers its hard to give you much info. The old 38 Long Colt round had a larger rim than the standard 38 spl. and also used a larger Dia. bullet - .361 just like the 38 S&W round .
On a side note , I have shot standard 38 spl. rounds in a 38 S&W cartridge revolver , the case's were buldged badly , yet were still able to be re-sized . You could try some standard 38's with a light load of Trail Boss and a cast bullet , BUT I don't think I would go much over that for now , this will also give you a case to measure for chamber numbers .
