I've been going thru my dad's garage and I found a couple of old books that look like the one in the pic above. Thinking of picking up his old stuff, like his old repair manuals and tools, and making kind of a retro area in my garage.
I saw this timing light and remembered my dad still has one that works and some other Sun test equipment from the early '60's. I know this is an old thread but I couldn't resist.
