Never heard of a red pin queen. Two thoughts come to mind....
One....this is a queen or queens, that came about by happenchance, and some beekeeper "coined" the term to market or feel special about their bees.
Two....Someone has spent a few years developing a line of bees, and has named them "red pin queens".
My money is on #1. Probably some combination of blend, a hybrid that came about. I would wonder if this is a selected line with specific criteria, or just a result of open mating with little control in the breeding efforts.
I have some really neat looking bees from time to time. The result is usually due to a lack of control of genetics. I never thought of slapping on a fancy name and marketing them as something new. Hmmmmm......
Mutts no more! "Bjorn's Evaluated, Selected, Traits"....... better known as "BEST" bees and queens! :lol:
I'll have to give this some more thought..... :?
