Some interesting stuff in the pic with the schematic - a round piece of paper with "E A D G" written on it and gauges? And HEAVY gauges?!! .060" .072" .098" .115" Is that from some ancient string set?

Looks like a relatively early one too, from San Francisco, much lower serial number than mine!

Mine didn't come with strings either, nor keys.  (Maybe that's why I always seem to be playing in the wrong key.)

Older than mine as well.
