Worryingly yet another one...

For when the link dies here’s a photo of the re-strike / ‘old stock’ (if you believe his pony story) next to one from Geoff Newman’s site. Geoff’s one clearly has some age and I wouldn’t doubt it as an original.
As you can see the badge is identical from the original die so a re-strike, also has same die cast appearance on the reverse, a correct BP mark and BP style slider.
The only slight difference I can see is the edges where the cypher crosses over appear blunter and less defined. On Geoff’s badge they’re sharper looking.
