Agreed on Master for first two. Last one could be a misformed Master, or WV swirl of a few companies.

Are we positive they're USA and not French?

I'm clueless with those but they look vintage

Ouch 😥

Thanks to all - I'd have been lost without this great resource and community (possibly better off but still 😉).

Have a good one over the pond.

Thanks for the update - I find the gallery pages very useful.

Thanks - yes that looks right.

New acquisition - any dating (or other info appreciated):

Bottom two are cheap Asian, the Alox are fakes (probably Marble King cats), the glass swan might be rebagged Jabo but I'm not sure.

Yes - Vitro All Red BlackLine

Agreed on Vitro Conqueror, Agreed on WV Swirl, although I'd lean Heaton if pushed - not sure on the far left, might be one of Champion's filament filled marbles rather Vitro, would want a closer look.

Can I throw Vitro Anacortes into the possibles - that teal looks plausible... Tricky one

I'm not convinced they were intentional - could easily be glass changes, but they could be the glassmaker playing around. Most larger bags seems to have one or two in them though and that seems a high percentage if they weren't intentional. Basically I'm on the fence 🙂

Colours look more Akro than Vitro to my eyes.
