I hadn't heard of Diodegonewild. Thanks for that. He seems a bit like Big Clive in terms of video style and content. I'm only going by the thumbnails so far.
I see he did a video on an old multimeter in the past week and this one you have seems of a similar vintage (ie. pretty old). So it may be of interest to him. I'd say send it to him, especially if it is cheaper for you.
