The Red C-3 Demi-Frame (Argus Half Frame Camera)
I cleaned and lubricated this old brick, changed the flash timing to synch for electronic units, then modified the body to expose 48 images per 24 exposure roll, each 24mm h x 17mm wide. Film plane gate was masked with inserts (mask parts are made from 1/8 inch foamboard painted black), a second film stop pin was installed into sprocket and gear set (sprocket wheel and gear were removed, then drilled) (pin was cut from a panelboard nail, I left on the head), and front viewfinder window was masked (a little black sticky vinyl shelf paper). Then I recovered the front in red leatherette cut from a photo album cover. It performed well in its inaugural film test.
Ed, wonderful stuff! I happened to find another C3 recently and thought of your old Half frame brick. Was this an easy enough hack? That is, is it something that a guy like me can do on his own?
