Apparently just looking at them can be deceptive, you almost have to take it for a ride to ensure it goes like a Red Hunter. ?
Plenty can have happened to them over the years.
At club night some time back, someone associated with ye olde time local Ariel Dealers mentioned that in the early 1950s, they had something like 50 orders for Red Hunters. The ship carrying them finally arrived, and they uncrated the 1st one - and it was black !. When examined closely, it wasn't a Red Hunter. And neither was any of the 50 of them. Not sure how they communicated with the factory, but it seems they didn't have enough parts to fill all the orders, so they just supplied what they could. The Dealer offered them to customers as "Black Hunters", at reduced cost. And offered a refund of deposits if the customer didn't want to proceed.
Perhaps painting it red would make them go faster ?
Food for thought ?
