Production of this Gallus model ceased in 1952. This example was produced late in the production and is labeled the Derlux, the final name given to these cameras. It is equipped with the Gallus Gallix f/3.5 50mm lens, as was the Derby Lux, as well as an accessory shoe. Others may have the much more uncommon and superior Boyer Saphir f/2.8, but the fine Berthiot lens that was found on many preWWII cameras from Gallus was not available.
It was not an inexpensive camera costing up to 25,000 Fr in 1950, or approximately $600.00 in 2006 currency. Although I can find no reference to production numbers, it apparently sold sufficiently well to populate eBay with a constant supply.
