The PHILCO Phorum

Does anyone have any information at all on one of these? I found a pathetic one on Ebay that needed saving. The guy wanted $30 for it but accepted $18, so it's on the way here. So far I have not been able to locate a schematic for it.

If it's in the case there might be a schematic on the inside cover like this one. Too bad it's too blurry to make out.

Thanks KCMike, it actually is still in the case, and I blew it up larger in the photo, and there is one in there. The paper appears to be blue, but it is on there. Cool!
