Do yours have that feature I described? Stopping the floating dial?I have several GI lensatic compasses , and find them often times at flea markets for fairly inexpensive prices . The Cammenga compasses are the most common but I have a Stocker and Yale along with a couple of other makes as well . My most recent purchased as a Korean War era compass made by Superior Magneto at the Tulsa Flea Market . You can buy GI compasses for less than $50 if you're not impatient unless you go to a surplus store then you will pay the full tarrif.
