I've been trying to get some concrete information about Interstate Engineering Corp., the makerss of Compact, Revelation and TriStar machines. I've always heard that they had a hand in the war time efforts of WWII building aircrafts or something related to them, but I can't get any detailed info. I've even seen some of the older Compact machines bearing a commemorative logo that shows an airplane, but that's the limit of my information. Does anyone know exactly what they built that got off the ground and saw war time activity?

Virtually every company with any sort of factory was producing something for military use during WWII. If not planes and bombs, then helmets or canteens or boot soles.

I know nothing of Interstate Engineering's contribution, but here's Hoover's history page on their war production.

I've also seen something on "Charles~Richard" Lester's site about Electrolux's wartime production. I'll give him a chance to plug his own site.

I guess I wasn't very specific. What I meant to inquire about was the fact that Interstate was making aircraft before they were making vacuums, not that the war effort caused them to change their factory. I was curious about the aircraft related production. Charles-Richard sent me a link that explained it all.
