Thanks indeed for such a detailed set of videos. When I was studying A-level applied maths in 1975, we were expected to use this type of calculator and were even allowed to use them in some exams. But electronic scientific calculators had just become a thing, following the launch of the HP35, so I never needed to use any of these mechanical calculators at uni or at work.

Thank you a lot for those videos! I found one similiar but newer model. I bought Model 13 from flea market the 19 April 2021 for 7,5 euros. But it was stuck all parts. I watched your videos and following restore and now it work perfect. Model 13 have some extra stuff and diffirent solution. But THANK YOU it was ONLY video restore of this type I found in internet! Keep continue! :) / Swedish guy

I’m glad you found the videos useful. I have two model 13s; an early green one with the carriage release button on the front, and a later grey one. Replacing the carriage is tricky on the 13, isn’t it?
