Copies letter without carbon paper

New on the market in 1931. 

Ingenious. Sounds fiddly though, especially when making more than one copy. Must be very specific to a particular model of machine to be able to use the paper guide to hold this extra device.

The extra feature that the copy also can be two-color probably did not outweigh the extra hassle. Also not sure it wouldn't smear the copy with ink during linefeed, needs to take care with inking levels.

In any case it was not a roaring success that drove carbon paper off the market - carbon paper can still be bought even today!

Come to think of it, carbon paper probably pre-dates typewriters as well. And after a very quick scan of the collection of niche interests that is the internet - yes it does!
