Deardorff 5x7 Camera

I recently purchased a Deardorff 5x7 camera from a friend of mine and fell in love with it right away. After I searched online for Deardorff 5x7 camera information, I learned that my camera was made during World War II period because the rear standard is made of cedar, not mahogany, the lens boards are 4.5x4.5 inch with round corners, there is no front swing and knobs are nickel plated. Deardorff 5x7 cameras were made without front swings from 1926 to 1949 and there were absolutely no identification of any form on them. 

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."
