I have a spare AC Owners Club badge for sale.
It's one of the recent aluminium replica's - it's the right size, though it is painted, rather than enamelled, but is a good approximation of the original British badges for a reasonable price; especially given the original badges now regularly exceed £150 for a good one.
I paid £30 for it, so you can have it for the same, plus postage; email me if you're interested and I'll send you a picture.
