Is there anyone on here that has (or can point me to) a Cannon connector catalog from the 1940-50 era? Specifically, I'm needing info on the "K" series and whether there is an "M" shell size. I have a 1965 catalog that lists an "N" size but there is no mention of an "M". Possibly the World War II radio manual I am looking at has a typo in the parts list.
I thought I would try this route before bothering Bill Perry.
