Going through an old storage chest I found the 7” Klines that my Dad gave me in 1948, when I was an apprentice. I recall him telling me that 7” Klines are for inside journeymen, 8” are for linemen. There is also a Wiggy that he gave me at about the same time. It also still works properly.
I also have a Triplett 310 that I received from a Triplett Rep in about 1962. The instruction book says “The Mighty Mite VOM”. It has a Model 10 AC clamp-on amp adapter and a Model 101 line separation adapter all in a leather case #379. I still use this meter from time to time. They just don’t makem like they used to.
I have always found the older tools interesting.
