Right out of a WWII B-29

I love the shape of the B-29. Japs would probably disagree....
I built an oscilloscope in the early 60s from WW2 surplus parts. Transistors were just starting to become available here for general use. I remember a Philips Germanium OC72 transistor cost a week's wage of a trainee technician. And that was trade price because my father was in the industry!
