I'm pretty sure I have a spare Bolin 12V motor knocking around somewhere in my spares if anyone needs one. I bought a couple of them directly from Sweden a few years ago, but later swapped to a 24V system with more chunky pumps when the refit was done in 2007 so it is redundant. (Don't recall what happened to the pump itself.)
