Below is quoted from Deardorff Historical Web site (Ken Hough)
"Deardorff 5x7 cameras came in 3 styles. The first had the sliding panel lock on the side of the front base with red wood and lacquered brass (circa 1926). The second version is red wood with gold hardware (1926-37). The third and final version was Brownish wood and nickel plated metal. A sub version of this was the WW II production cameras. These camera were made of Spanish Cedar ( yellow in color ) with some mahogany. The metal is nickel plated. These had 4 1/2 X 4 1/2 square cornered lens board on the earlier models and in 1937 went to a 4 1/2 X 4 1/2 rounded cornered lens board. Production ended in 1949 with the introduction of the V4 and V5 with front swings."
