I can't begin to tell you how fed up I am of finding odd curious things! (and not just glass). Life would be much easier

I think I must attract the odd and curious, which probably says a bit about me also

Thanks for the links. I immediately thought Art Deco when I saw these, but on the second link Chris Stewart says that Davidsons produced quite a bit of matt black in the 1950s.
I must confess to really liking matt black rather than high gloss, it looks so much classier IMHO.
