my first TC had the intercomm, it was hard wired. I think it was a Heathkit. The camper was an unknown mfg. but had 1959 stamped on the dataplate. The intercomm in the camper had a hugh, heavy 10" speaker mounted on the side of a cabinet. Great sound. The truck half had a big, steel cased microphone. Probably weighd two pounds. Pre-transistor it had a couple of vacuum tubes. Took a few minutes to warm up. Just too cool. It went with the camper. Shoulda kept it.
Just found a complete set of that Heathkit Intercom, and the two different models of the Philips InterCom kit that the Amerigos used.
