Product code: Vintage Supreme Instruments Corp Model 589-A Portable Battery Vacuum Tube cheapest Tester
This cheapest is untested. I freed up the rusty hinges but have done no testing. The cord is stiff but appears undamaged (so far!). Leather handle still works. Sold as is, for parts. Looks pretty still!.
