Sometimes while roaming around on E bay looking at parts I run across something that is impossible to ignore. That happened last week. I came across 4 old Westinghouse Microwave emitter tubes. They look to be surplus U.S. Navy parts from about the late 40's to late 50's (A prime time for robot parts).
They were a good deal (11.50 ea) so I ordered them right away. When they got here they looked even better than expected. I am not sure what they will end up in, half the fun of doing this is figuring it ll out, but I am positive they are heads.
Screams Robot Head to Me!
