At the Ada hamfest I got a DIELECTRIC PROD. ENG. CO. INC Raymond, Maine, Smith Chart Impedance Plotter, Type No. 100P. It was in a nice wooden box, no accesories but included a 1971 gov't invoice of $1125.00 transferring it from Ft. Belvoir to Kelly AFB. I've put a couple of pix up at alt.binaries.pictures.radio. I haven't opened it up yet and nothing on Google except the companies site with no info, I'm sure they consider it obsolete but I've sent them a query. Any info apprecaited. tnx
