[ARC5] Radio hunting...

[Craig Cantwell]

 Mark: It's for a potential project that's been cooking on the back burner for a number of years. Not sure if it's still going to be viable, but I've been slowly chasing all the parts that are unique to it as well, since I've found most of the AT stuff now. Radio and weapons stuff is all pre and early war items, with some being straight commercial products. The radios were essentially the same as the commercial versions, with not much more than a data plate added from what I've been able to find so far. I've managed to locate a number of Bendix drawings for the radio and it's mounts, the control head and other ancillary bits and pieces. I just need to do some letter writing and check writing to order them.
Been working on converting drawings for the AT for a bit and have done a bit over 1000 drawings. There are probably another 4500+ to do, along with probably another 2000 pages of various documents on the film. I'm starting to inventory parts that can be restored. There are boxes and boxes of parts in the warehouse and I can now identify most of them and tag them with part numbers. 
Plan is to move and inventory all the AT radio stuff this holiday weekend and start working on dynamotors first. Still have some mounts and plugs to hunt down, but still need to do a full inventory before ordering anything more. Too many boxes spread out between various locations right now!

I wanted to put the word out on a couple of radios that I'm hunting for a project. Quite oddball and haven't found but a couple, and they were all overseas and not available.
I'm hunting for:
Bendix TA-6A or TA-6B transmitter, A or B only differentiates between 14 or 28 VDC for power. Either will work on this project.Bendix MT-54 control head for the TA-6RCA  AVT-7 transmitter
One TA-6 popped up about 2-3 years ago in Australia and went to a private collection, and the seller no longer has any contact info on the new owner. I haven't found another anywhere in the world, even in a museum, in over a year searching.
There are two of the AVT-7's known and both are in Finland. One is in the Finnish Air Force Museum and the send was sold to a private collector in Finland, and didn't appear to be a complete unit.
Leads on locating any of these would be most helpful.
