Many thanks, AB and Mamya! My golly, that RHONE one
was contrived! I broke away from the Skeleton 10 years
ago and was doing its counterpart in the MOS, but this became too easy and I recently went back to the Skeleton.
I'm a glutton for punishment!
Sorry, my attempt at underlining and Italics using tags didn't work!
The solution is:
21D [Equipment = GEAR] (working right,#right-hand letter# > G) (one hears = EAR) > G+EAR
