Does anyone have very old (1950s) transistors (or know of a collection/semiconductor museum with any)?
I am interested in photos of them and, if possible, simple tests to be carried out on these grey-haired old timers. I'm also interested in reports of anyone with old (preferably pre-"OC71") transistors, or interesting rare germanium and early silicon transistors. Also I could be interested in buying germanium transistors including the not-so-rare AC126/128 series, but it looks like there are plenty of places to find old 2N- types.
