Grigg,

I think your new project has a WW2 military G506 bed, most likely made by Budd. There were a few changes in the bed depending on wartime resource availability so making a relatively good ID of vintage is not too difficult. If you take some pictures I can help you out.

Cool saga, I bet it was difficult to pay attention at your conference.
