George A. Philbrick Model 5934 Original Manual 1964 analog computer.

Maybe the only copy in existence. I tried to auction this a few years ago and it didn’t sell then and I found it back in a box because someone was asking for it a few months ago so I’m re-listing it as a buy it now.

Originally obtained directly from George Philbrick as he and my father were good friends and he used to test Philbrick products out for George.

Since all my eBay photos from this last auction were posted on the Philbrick archive I have decided not to put as many up this time . It’s a 50+ page manual with all the diagrams too .
