WWI Creagh Osborne Marching Compass W/Case & Original Instructions

Description

Nice World War I Creagh Osborne Marching Compass.
This is the Mark VII Model E made by Sperry Gyroscope Co., Brooklyn NY.
The Compass is in overall good condition considering the age. The liquid is still inside, but it has darkened making it hard to read the dial. The leather case is in good condition also. It is still in tact with the exception of one side of the cover flap hold down. The small glass lens is in the opening on the side, but it is loose in the housing.
The original instruction is included as well. This was folded up inside the case and has some tears.
Please see the pictures for condition.
This is an estate find and is being sold as is as found, I have no other information about this item.
this is a great piece of WWI Military Memorabilia, perfect for any collection !
