Kodak Instamatic 104
These cameras were manufactured from 1965-1968, and this one appears to have been used solidly since then.
Specs : f/11 43mm lens, shutter speeds of 1/40 and 1/90, uses 126 cartridge film giving a negative size of 28x28mm. Originally sold for US$15.95.
They used flashcubes rather than individual bulbs (invoking memories of my earliest photographic attempts).
