Friden STW 10 mechanical calculator

This has been my most difficult mechanical device restoration to date. But once repaired, what a machine! Then it got famous on the 'net for dividing by zero.

Facit TK mechanical calculator

A 1936 small calculator design that pioneered serial entry and would endure for 30 years.

Solari Dator 10

From 1957, this is the ultimate Italian flip clock, used in railway stations, airports and banks.

IBM Selectric II Typewriter

The second edition of the famous "golf ball" Selectric typewriter that took over the market in the 1960's. This one even has the erase button.


Model 19 and Model 15 Teletypes

Conceived in the 1930's and in use until the 1980's, these mechanical marvels are the first form of digital communication equipment. So they double count as computer and mechanical restoration.
