Pic 6: WMF 'Ikora' glass, Germany, 1930's - unfortunately, missing its double-headed screw-in chromed 'head' for bulb holders (note the thread to the inner rim of the chrome fitting).
Pic 7 - Top Shelf: Item 6 (l to r) - see comments below. Item 11 - Czech 1930's.
Pic 7 - Bottom Shelf: Items 3, 4 & 5 (as item 6 above) - These are regarded by many as Nazeing. However, I have not been able to confirm that this is indeed the case. I even used one of these as an illustration in the 'Miller's Guide to Collecting the 50's and 60's' (like the green ovoid form with a clear bun form base that you have) :oops: I gained some extra information just prior to holding the "Nazeing Glass and its Origins" exhibition, which threw doubt on their origin. I therefore question the attribution, but understand people's wish to use it.
Pic 8: I agree with Frank about the origins of these pieces.
Pic 10: Not in my normal remit, but the green and blue irridised piece looks like Loetz. Does it have a nicely polished out concave pontil?
Pic 14: Morag Gordon, England 1980's. These pieces normally have an incised signature to the base, along with other information (which illudes my mind at present). These pieces are particularly beautiful and if you can get them in the right light, stunning! How big is your version?
Kind regards, Nigel
