1941 Underwood Champion Serial # G1420372 1941 Underwood Champion typewriter, Serial # G1420372 Piotr Trumpiel's 1941 Underwood Champion typewriter. 2014-11-27 From the Virtual Typewriter Collection of Piotr Trumpiel: 1941 Underwood Champion Serial # G1420372 Champion. It had an issue with ribbon transport. I couldn't figure it out at first so I put the machine aside. Now I wanted to take a closer look.
It seemed the mechanism worked as it should however the spools moved for a while then stopped. They are DIN 32755 ones (53.65mm diameter) - clearly someone put them in as a replacement.

My theory was that their bottom ring is catching on the sides of spool cups as they wobbled a bit on the axis. I didn't have an original spools to try so I decided to trim the ones that were inside - since they were plastic ones - and voila!

A transformation - the machine now types easily, the imprint is clean and crisp. You can see a new typeface specimen sample within the photos below - I haven't changed the ribbon...

Now it is a machine that can live up to its name.
