Ron, Thanks for the detail about Philco's serial numbering system, it makes how they did things clearer.

Also, thanks for the rant - you make a very good point. I find myself a little eager for info since I just came across an early model 90 and found myself wanting to know if any of the three versions are considered scarce (they seem about equal). Again, thanks for bringing into focus what it's all about....having that radio - fixing it and enjoying it !

For Ed, My cabinet bottom is stamped "May 1931" and has " # 7 " written in blue marker. The chassis has no serial number on the back pannel.
