I recently aquired an early Randall 7 spacer model 23 gamemaster.
This model was developed in late 1971 or early 1972 and first appears in the 22nd printing Randall catalog in 1972.
This gamemaster is an early example, as the spacer count on non-leather handles went from 7 to 5 in 1972.
It's fun trying to find early examples of any particular Randall model you like.
