1957 - Bohn Contex 10 Mechanical Calculator In Depth Look

This is such a cool little device, an all mechanical calculator with a keypad input that supports the four big functions. This thing rocks! After going back and re-reading the page I mentioned that used foam to repair one of these ( https://www.csparks.com/contex/ ) it definitely looks like I'll be needing to do that as well. It's a shame that foam was used since it is such a degradable part.
