I have checked and there are Gillette Super Adjustables for the 1970 quarters P-1 through P-4 and the 1971 quarters R-1 through R-4 but there are also Q-1 and R-R.
Has anyone solved the riddle of when the Q-1 and R-R razors were made (what year and quarter)? There seems to be plenty enough of the Q-1's that they aren't one-offs - about ten were sold on ebay in the first quarter of 2015. The R-R seems a little more rare but from the B&B posts a few people have them. Anybody know more about them (the Q-1 and the R-R) other than they exist?
