Thanks J E
The best I can find so far is a fuzzy copy of a 1960-something reloading manual...
0.472 rim dia., .471base dia., .402 shoulder dia..
The shoulder is 1.820 from the rim and the brass is 2.221 long. I could be a little off because of the poor condition of the copy.
I was hoping someone else had a more ledgeable copy.
