Name, rank and number

Name: Yashica
Rank: Mat
Number: MT 2030216
That is, the 216th Yashica-Mat camera to be manufactured in March of 1962. The model had been introduced by the Yashica company in 1957, the 'Mat' signifying autoMATic shutter cocking. (This meant, turn the film winder away from you to wind on the frames, then reverse it to cock the shutter.)
The original Yashima company formed the camera name by merging YASHIma and CAmera to become Yashica.
