IBM-made 70-key (US English) or 71-key (rest of world) electronic typewriter keyboard assembly for the IBM 6747 Wheelwriter 5. It's presently the earliest known Model M-based keyboard design. Characteristic of an early Wheelwriter/Quietwriter keyboard assembly is its use of O-rings and "cushionless" rockers that result in a slightly different key feel to other Model Ms.
