Need semi-globe light fixtures

I thought I posted this on the "new-improved" Chatterbox Lounge, but it's not there...

I'm looking some of the original "half round" or "low profile" white glass fixtures that were used in hallways, bathrooms and as outdoor fixtures in 1955 period (maybe later) Eichlers. There's one shown on the cover of the new Eichler book. I need 4 and will pay dearly!

Thanks :)
