Description

Vintage Pickett & Eckel Chicago IL Slide Rule Model 600 Synchro Scale In Case
Buzz Adrin and Neil Armstrong used a similar model 600 on Apollo and Gemini missions.
There are a lot of websites documenting the use of Pickett Model 600 on the internet.   The exact model used for each flight was not documented.  There as a couple of NASA astronaut used and documented Model 600-ES that have sold for significant money.   Mine is a model 600, not 600-ES, but it is an early model 600 that fits the timeframe.
Excellent condition!
