Here's a photo I took yesterday on the cavity of my '74 4001.
Any idea of what any of it means? I'm intrigued!

Hmm, I had Arnquist decipher my 73, He tells me the workers sometimes drew pictures and got quite elaborate! He ID'ed some of the bits in my 73 4001.

Ernie and John signed off on the work they did on this instrument. The letter following the model number is a batch indicator. Don't know what the other numbers mean.
