[I didn't know they are mahogany, mine definitely didn't feel like it. But if they all are, tempting.
All cameras made by Folmer and Schwing Manufacturing Company from their beginning in the late 1890's through 1922 are made from Honduran Mahogany, covered in XXX Moroccan leather with silver plated brass hardware.
1923 the hardware plating was changed to paint.
1947 the body covering changed to leatherette, aka Naugahyde until the end of the company in 1973.
1949 saw the introduction of a Bakelite body camera, the Century Graphic, a 2 1/4 x 3 1/4 similar to the Crown Graphic. All other 2x3 and larger format cameras remained Naugahyde covered Mahogany with various platting or paint on brass hardware.
The thickness of the body covering is figured into the size of the other camera parts so when stripping a body the back, bed, FPS roller bearings and control plates have to be shimmed the covering thickness to fit and work properly.
