[SML] Looking for Glass Vaporproof globes

[P. Dunesky]

Dear List, a bit of a plea from Oz here, and not necessarily theatre related
but maybe...
I am looking for replacement Clear Glass Globes for some Paul Uhn brand
industrial light fixtures, the kind that have a plastic shade and a screw on
cage protecting a screw on glass globe with a 200/300w lamp inside. I bought
these as advertised as Titanic Deck Light reproductions but the protective
glass globes are cracked.
I have looked high and low and have even bought a couple off Ebay but the
thread diameter was only 4 1/2".
The ones I need measure 9" long by 4 3/4" across the thread.
The fixture itself is die cast aluminium with a bakelite E27 lampholder
mounted to it and is marked Paul Uhn Hou. TX. P36.
Any help locating a source for these glass globes would be greatfully
received!
Cheers from Sydney Australia! PhilD
