"I've never known these 2 gentlemen to be Randall dealers. I've always thought they were very good acquaintances, customers of Randall.
Have I missed, or overlooked this subject somehow?"

Gaddis mentions Ward Gay ordering up to 12 of his specials at one time. It's known that Bish built a good number of "kit" knives too. That may not mean they were actually dealers, in the strictest definition. I guess perhaps the description of them as a "source" for Randall knives would be better. ? Maybe ?
