Marked on the brass cover F Barker & Son, Makers London No. 22 1917. I assume 1917 is the date of manufacture and 22 is either the model or serial number. It appears to be working, it moves quite freely but has been settling in with proper north. Wheel locks when sight is folded down. Had the military arrow mark on the cover as well. Shows some wear including scratches. Has threaded hole on the bottom for a tripod or stand.Please view all 24 photos for measurements and condition.
