I have 2 figurines with the same mark, an N inside an O or circle. Would like to know more about them.
Sounds like the infamous CN/NC mark, *sigh* ...
Problem is that nobody so far has offered VERIFYABLE proof of origin as the same mark is found on dozens of Asian figures, many of them produced at/for Arnart, HomCo, Napco Py, Norcrest and others. Even the most logical assumption of it being [N]or[C]rest is misleading as that would rule out others - but that in turn collides with proof of items showing combinations of exactly that mark together with other distributor/manufacturer marks.
With other words: I admit that I have no idea but that is perhaps a better answer than the many claims of origin that are as watertight as a sieve.
