This firearm was apparently manufactured in 1952, the X proceeding the s/n implies that it has a 2 3/4" chamber as opposed to the old 2 9/16" chamber. High condition Auto 5s are becoming somewhat collectable, especially the Sweet Sixteen and a high grade one in "new in box" condition (with the original shipping box) might bring as much a 2 grand if you could find the right collector.
