David,
To be honest I think Mark has had a bargain and probably paid £50-60 less than its true worth (?), the other one at £225 is also a snip and had I not recently acquired one I would have snapped it up! (I see that one has now gone too
).
This is yet another badge, that has been faked that much that it reduced the selling price of originals as people are reluctant to splash the cash in cash they end up with a dud!
I had gone 40 years without seeing a genuine example of this rare badge on the open market and within the space of a few weeks three have appeared, perhaps just a fluke but these are pretty scarce badges!
