Greg, he got it from morgan and wackers the long term Harley/BM dealers here. I bought my BM's from them 30 odd years ago. They have put new panniers on the bike at a discount price, upped the price of the bike to suit and it's gone through finance just fine
He's picking it up today.
I was at the bm shop Friday getting an air filter for mine. More oily industrial unit than shop
