EB minibucker ring - legit vintage or reissue?

[Granny Gremlin]

I been vaguely looking for one of these for as long as any of you have known me (hard to find one without a pup attached, not too urgent as I have one, but it's cracked and missing one side so eventually...), but this one, though listed as vintage, really looks like an Epi reissue to me (shiney new, tooling marks on the inside and really angular; I seem to recall the edges being slightly more rounded over on the 60s ones but I'm not at home right now to check - and yes I do realise that the seller says his is 70s, and there may be a difference there; that's why I am asking).

What say youze?

The Epi reissues are metric vs SAE so the vintage pups don't fit ... but I don't know about the Gibson reissues (e.g. SG bass, all the new hollowbody models etc - anything with a mini on it); anybody know if those will fit a vintage pup?
