Mine is like this, but was made in the 50’s.

Those are awesome accurate and sweet as hell ..... want one baaaaad. Used to get issued such but they kept better track of those than PVS-14 Night Vision. Don’t think I ever saw that Brunton transit / compass fall off a truck .....:o)
Made in the 50’s ? Wow, wonder what quality difference is from then to now. Current everything seems to be cheaper and weak these days. Bet your old one is best still.
Stay safe !
