My son has been cleaning out former comm and navigation sites prior to demolition and keeps finding some old stuff.  The interesting things he keeps or gives to me, one is a M15/UR hand mic made by Roanwell, Corp. that looks like the T17's.    The element has a spacer behind it with 8 rectangular tunnels where you can see between the mic body and the mic element.  It has a 3/16 plug, this one may have a wire, plug, or switch problem as I tried it with the ART 13 this morning and got no key.  Anybody know the history of this variation of the T17?

He found this roll around table that I and all of my coworkers have never seen before, and any that might have are all passed on now.  Underneath is a sticker, " Made by Nichols Manufacturing, Memphis 11, Tenn.  Office and Television Stands", and this has been in this facility since commissioning in 1953.  There is no reference to this company online.  It has two adjustable racks above the split wooden table.  Anybody have a clue what this might have been used for?
