Aha! Thank you. I knew the Mk2 was close! I assume it’s functionally identical to the mk2?
Sadly, I got precisely zero info with it, as it was from a garage clearance sale.
I will have a scoot around on here for some more info, as obviously at least one other is running the same kit.
I don’t suppose anyone might have a pdf manual kicking about?
Oh, and thanks for the tip on posting pics!
