When I was at the recycler last week, I saw a lot of really OLD test equipment. I started looking through it to see if there were things I could recognize, but the closest thing I could figure out was a 1940s telephone equipment tester. All of these were portable, with lids that closed with latches. Probably weighed abt 20-30 pounds each. Any cables that might have been needed to run the equipment was gone. If things like this are of interest in the $25 range, then I can pick some up next time I see them. Unfortunately I have no cell phone numbers for anyone in the DFW area to tell them to come and see the goodies while I am there, and they will not let strangers come in and poke around. I am (or was) an electronics tech, but most of the functions on these old test machines eluded me. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
