Lol! It's always fun to hear stories about experiences with these old devices.
My only experience with the model 43 (actually the very unit I'm working on) was with it connected to a transmitter remote control system called a Moseley MRC-1 at a TV station I used to work at. The model 43 was mainly used to print out transmitter readings at regular intervals for the master control operator. I didn't learn until just the other day that the 43 could have been used to control channels on the remote control to do things such as raise and lower transmitter power, turn the transmitter on and off, etc. When the MRC-1 was replaced, I made sure to squirrel-away the model 43 since it otherwise would have been tossed in the dumpster. I've had it in storage for about 20 years now and I figured it was time to get her cleaned up and working again.
Here is a brochure for the Moseley MRC-1 - which includes a photo of a model 43:
