Actually the first iteration I know of was the 38/45 which came out in 1963. Since then there have been a number of variations in respect of minor changes to dimensions and parent case (45 ACP vs 45 Win Mag vs 308 etc). Names include 38/45 Clerke, 38 Casull, 45/38 Hard Head, JWH etc. Main result of the egos at work is that there isn't a standard chamber, dimensions, dies or brass, load data etc.

You pays your money and take your chances.
