[Today’s run: resting up for race tomorrow ]
A few years ago I happened to be in the right place at the right time to inherit a big homebrew AM ham transmitter. I had some fun with it and I passed it on to someone else when we decided to move from Colorado to Mississippi.
At the same time I received the AM transmitter I also received some odds and ends. One of the items was this thing. 
It appears to be a VHF or UHF AM transmitter. The front has various controls and meters. The side panels open up to show the tube-base wiring. Tubes are actually accessed from the back. No sign of a VFO or frequency indicator. There is a crystal socket on the front. The meter in the center could be switched to monitor three stages of frequency multiplication. It stood about 4 feet tall, about 30 inches wide.
It had been modified with a different output network. It had an 829 final tube in it. The 829 came out in 1940 and will produce about 80 watts up into the UHF range.
It did have some nice transformers in there, and lots more tubes. There was an audio section.
Maybe it was a single frequency AM transmitter, from an airport or something?
When it came time to move I gutted it out, kept all of the tubes, tube sockets, transformers, meters, etc. and got rid of the chassis. I am kind of hoping someone will come along someday and say, “Hey! I used to have one of those!” I realize the odds are very slim.
