Both units look like Northern Electric MKIIIs. They're in pretty rough shape (cosmetically) but in the right hands should clean up well. There is a crystal calibrator which isn't very common these days. The empty box it is sitting in is for the power supply that is in the big box.
One control box is missing the drop plug, can't tell about the other one. Variometer is there on what looks like a #23 carrier. Spare valve box looks reasonably complete.
Considering your friend dropped by and gave them to you consider it a good bargain. Whether you are doing armour, softskin or just ground station this set was the most common one used by the commonwealth forces.
If you don't want to do the work I'm sure there are those who will come out of the woodwork to relieve you of them
Even from Texas.
