FS: Field Sky Screen

Post by VC-1 » Sun Jul 30, 2017 6:44 am

OPTOmechanisms Inc. (Mineola, NY) U.S. Army Field Sky Screen optical chronograph. As you cannon cockers know, for measuring muzzle velocity in field artillery applications. Just the unit, don't have the pressure mat as been described to me. Interesting little Unertl spotting scope mounted topside. Serial num. 8.

Only real manual reference I've been able to find is a quick mention of: TM 9-1860-7 Operation and Organizational Maint. Field Sky Screen dated 1959. Anyone with this manual?
If you're interested in this item we need to talk, it's quite hefty. Pictures available.

Thanks!
