Just a 'heads-up' in case anyone is interested.
While searching for P&M Panther parts on eBay I came across this company selling bike prints.
They have a lot of Ariels (and other makes too).

They look good, but I haven't seen one 'in the flesh' so can't comment.
nothing to do with me, I just thought someone might be interested.
(Why is it that they don't have any prints of the bikes that I have actually owned??? - three Ariels, four BMWs, 1 Panther . . Grrrrr
