Years ago I picked up a Canadian WW2 National HRO receiver at a surplus store. Heavy, and with a thick metal plate meant to be mounted in a panel, and a separate transformer, I enjoyed listening to short wave broadcasts, ship communications, etc., for a long time. It stopped working- probably one of the 12 tubes quit- and I never bothered to fix it. All the pbs FM, etc., had come in (it had no insert for the FM band) and I lost interest.
I am looking for a home for it. There is a large military museum here, perhaps they might be interested.

At a yard sale I picked up some old aircraft dials and the restorer people were very happy to get them.
