I have two Heath / Heathkit weather stations, one a ID-4001 and the other a ID1290. Both appear to work, though I can't guarantee it, as I bought them on a whim and never used them. I believe I have docs for them, and I know I have one complete sending unit (anemometer and direction) and one incomplete one for parts, or rebuilding if you're handy.
Best of all I'm asking $175 plus shipping for all of it, and will be happy to take more pics if you would like.
I will pack carefully to ensure everything arrives safely.
I'm happy to answer any questions.
