Remington R17 Pullball Onyx scales Red pull automatic knife

Remington R17 pull ball switchblade made by the George Schrade Knife Co of Bridgeport, CT sometime between 1937 and 1944. The knife measures 2 7/8" closed and 5 inches open including the plastic release ball which is red. The blade is nearly full  and shiny with some light scratches and a little light spotting. It's stamped Remington PAT 11-9-37 on the front and R17 on the rear of the tang. The Onyx colored scales are in very nice condition with no cracks or chips. The knife works perfectly! Nice old Remington switchblade from the late 1930s, or early 40s. EX condition
