The Cossor 1428 Oscillograph Camera (about 1953-1961) was a fixed focus camera for recording wave images. It used 35mm (135) film rolled into special cartridges. It was used predominantly for scientific purposes[1] and could be fitted to the Cossor double beam oscillograph, models 1035 and 1049. The camera depicted here is fitted with electric motor drive unit Cossor 1429 Type F with gear speeds of 4"/sec, 12"/sec and 36"/sec.—The drive unit is comprised of a Klaxon model EM5681 2760rpm motor, a gear box and the transformer and capacitor unit. The total camera unit weighs 7.0 kg.—When exposures were taken, the film was moved before the screen while the time base of the scope was switched off.
