The Compass camera was designed by Noel Pemberton Billing. It demonstrated great flexibility, being capable of use with 24 x 36mm glass plates or a roll-film back. Unusual and innovative in design, this high-quality model was patented in May 1936 and an estimated 5,000 were manufactured before the second world war halted production.
