Triumph Tippa 1 - carriage rack frame repair

I bought this small typewriter when I was searching for Olympia Splendid. Both share the same streamlined body and are very small and reliable typewriters. Now, when I own both, I know that they are, however, quite different mechanically.

This Triumph Tippa was my kid’s a favourite machine - because of its light colour, in contrast to my other machines which are mostly dark in colour and much bigger. However - she does not use it and I have too many machines so I consider giving it away or selling.

As to be sure that I trade a functional typewriter I cleaned it again and run extensive diagnostics - which is typing on it really fast. All seamed good until I noticed that it jumps a letter in one certain position along the carriage.

I took a closer look and discovered a problem. I describe how I handle it in more details here.
