“Double Pigeon” Model DHY Typewriter

This is a “Double Pigeon” Model DHY typewriter that was manufactured by the Shanghai Calculator and Typewriter Manufacturing Works of Shanghai, China around 1974. The typewriter is made to print Chinese characters. The character is selected, inked, and printed by the machine, in a somewhat tedious process due to the 2,500 characters available and the fact that each typist could change the organization of the type tray to fit their writing style, varying the organization from machine to machine. Other character sets can be placed in the machine, allowing it to print over 7,000 unique characters. The typewriter was acquired to be displayed in the bicentennial exhibit "A Nation of Nations."
