OK, got the Model 78 into the list...it is nearly identical to the 11A. Only difference is the end pad for the draglink is bent to parallel with the splined pad. It was replaced by the 11A for parts replacement purposes.
Probably don't have '35-6, but certainly have a 21A and an F1. Will keep looking.
