This Shu Zhendong Chinese typewriter developed by the Commercial Press in Shanghai in the 1920s was the country’s first mass-manufactured typewriter. It is a remarkable intricate piece of machinery that testifies to Chinese ingenuity in solving the puzzle of how to type in a language with thousands of characters. MOCA holds one of only three such typewriters in existence in the Western Hemisphere.
There are many moving parts to this machine that are loose, cracking, and corroding. The wood base and drawer are warped and cracked. The rubber cylinders, stoppers, and feet have lost their shape and are tacky.
The machine has a heavy buildup of oily grime over all surfaces. This grime has accelerated corrosion such as to the copper alloy components that hold the printing tape. All surfaces of the typewriter have many abrasions, scratches, accretions, and water stain tidelines.
