Colours do look very vitro - I'd edge that way

Imperial I think

I'm pretty sure it's Jabo.

West Virginian Swirl is as close as I get. I don't think it's a Peltier either.

If in doubt I go Akro, and with lack of any characteristic traits towards one of the other slag makers... 😊

I agree with Steph - some of these older 'Imperial' are attractive marbles.

90% certain it's a Vitro Cat

I'd lean transistional on that last photo

I'd lean Marble King

I grew up with Dr Who (Tom Baker was 'my Doctor'), and was glad to see the relaunched series, but found it got too silly over the past few seasons. I tried the new series with low expectations, but was really impressed. It felt much more like the Doctor Who of my childhood than any of the recent seasons.

Have a great Christmas to those that celebrate and an equally great few days to those that don't.

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 😥
