I imagine that to some typewriter collectors are just marginally more sane than the Collyer brothers. I have, at some time fallen victim to a little bit of harmless hoarding. Attempting to divest myself of unused objects and help the Classroom Typewriter Project I have decided to offer my Hermes adding machine up for trade.
Count on me!
It's a lovely example of vintage office machinery. It can add and subtract! The gentle late 60s green-grey would match any of your late 60s Hermes equipment. It's 100% functional and in fairly good condition. None of the plastic is broken or cracked. It does include the paper tape that is approximately 1,000 years old and a little brittle. Fun!
If you are interested in trading this machine for a functioning manual typewriter, let me know.
