Hi Anne...
Sorry I read it and started looking online.Then replies to Kev.i though I could reply to each message individually but I could not so my ignorance.
That’s great info hence why I started searches again.I believe your right about the flat spot on the 8 looking at other dated pieces and I have another piece that came with this that looks very similar maybe all 3 piece were Davidson’s.I will add the other pieces tomorrow in separate links maybe the collector had a thing for Davidson Glass but neither of the other pieces are marked for anyone.
That’s a very nice piece you show in your image too.Im starting to look at pressed glass in a different light I have had some nice pieces in the past but tend to ignore it unless something specific peaks my radar.
So again apologies but your info got me searching again.

And maybe this is the piece Chris Stewart mentioned.
Thanks for your help
