A clipping from GE's 1953 "MERCURY LAMPS AND BALLASTS" brochure, a lot of data:

Fascinating, wouldn't mind a copy of this. If anyone sees one available anywhere, let me know 

 I'll keep an eye out . I found mine on eBay .

Thanks, Tim 

Intersting stuff, would even be interested in a digital copy seeing as finding an original might be hard as this point.
