There was a Chris in trade sales that I remember, who's surname *might* have been Robinson, but I can't be certain.
The naming wasn't usually done by the sculptors from memory, but it could feasibly have been a random person one of the Perrys knew, or whoever put the catalogue page/advert together. At that point it was probably Richard Helliwell (not Halliwell the sadly missed designer) who did it, but this is all a bit vague in my memory. I remember 'inking' figures with that shoe polish that used to come in a bottle with a sponge on the end for photography at one point for him.
I think possibly my most favourite 'comedy' naming conventions that I can think of is the early Imperial Army:
These are mostly based on Prog rock musicians, so you've got Brock, Davey, Powell, Lloyd-Langton, Calvert and Turner from Hawkwind (possibly also Thompson but spelled Thomson), Emerson, Lake and Palmer, (From Emerson, Lake and Palmer!) Lee, Lifeson and Peart from Rush, And presumably Female Trooper (Kate) Bush. I'm sure there are others I've missed.
Yeah, there are likely plenty with other connections, but I was told back in the day that these were all/mostly musicians. I'd assumed Bruce was Springsteen tbh.
The only exceptions I'd have thought were (Basil) Rathbone and (David) Niven and Laurel & Hardy.
of course, if you are going with the surnames thing, and sine there is Rathbone, I would say Bruce would be Nigel Bruce who was Watson to Rathbone's Holmes (though I like them films, and the Radio series, He is a pretty bad Watson in that he is the bumbling side kick which Watson wasn't)
