If you are talking about the mount you found on ebay, I tried to get it but the other guy was doing anything to get it. We fought until it reached almost $200. He got the last second bid and won. So I still need one.

We have a lot of welding to do, I used an air hammer with a chisel attachment to chip away all the tar crap that lined the bottom. Kept the original paint in nice shape though!

My Transmitter came in today, It looks fanastic! Vacume tubes are intact, and eveything is there. The freight company did break the brass door stops :evil: , but I suppose I can live with that :roll: A few lose screws, dead 60 yr old bateries, and a feild made fuse is all I have to address!

(ORIGINAL PHOTOS LOST)

The original set of radios I purchased were stolen. I recently purchased a new TCS-14 set. Photos will be added as soon as they arrive.

That tar was on a lot of MZ-2. :D

The batteries are a bubba thing as the TCS did not have batteries but used on of several power supplies.

Your TCS-5 is one of the earlier versions. There was some kind of significant change at TCS-8 and there are quite a few TCS-12 used.

You need manuals... at least one and maybe several.

Here are some... you find them on Ebay and some of the old radio and boat anchor (Navy radio) shops.

CUZ-50159
U.S. Television Manufacturing Corp.
Contract NXsr-48301 Contract dated February 1, 1944

Plus cables for the transmitter, receiver and remote, telegraph key, microphones, headsets and other stuff. As in all these type installations, the was a pile of bits and pieces that came with the radio system.

The antenna is a frabricated sheet metal box that contains the loading coil. I know Robin worked up the measurements from mine. I used measurements, diagrams and photos to make the one up on my jeep and others have copied that pattern until an original, if found, can be used for a template. The antenna base used was an MP-37 with antenna sections MS-49 to MS-53 in a BG-56 bag.

Man, theres a genny shroud too! Looks like we still have a long way to go. At least we aquired the transmitter and receiver. A friend has an M8 Greyhound 12 volt genny he says may be what I need. So I need to verify that. Right now, we are gonna start taking it slow, as we repait the tub and clean the frame. Thanks for the info Mark.

The 12v generator will look like this:

Note the small pulley, but your 12v one will have a green tag instead of the 24v off white tag like mine.

Hi EJB! :D

The antenna loading coil that is in this box comes out and installs in the antenna mount on the side of the jeep. The 6 position knob is under that front cover.

Image

One of the instruction manuals/pamplets had a Drawing 121 that shows a section thru the antenna box.

Here is a close up of that detail.

Instead of the BG-67 cover, I opted to use a Navy numbered antenna base cover instead.
