I found a sprintmaster rim on ebay the other day (finished now). It had me a little puzzled to what it was. It has a CSA center cap but no CSA/WIA cast into the front of the spokes. It also had a 6th month 72 date cast in the rear but has tapered wheel nuts not self locators..? Did they ever make a 6/72 sprintmaster that used tapered nuts or were thay all self locators?
