• It mounts on the same tri-pod/point where the 12.7 browning was mounted. The mount was a ball type mount.

• I finally found out about these lamps ! I had one I got surplus 50 yr s ago and today I found out the exact purpose.They clamped to to a top fixture of either a telescope or binoculars ( aboard ship ) and
  and were used only at night to send traffic from ship to ship.I assume the different lens shades were selected based on light conditions at the time it was being used.I only know of about 8 of these lamps in the world but there may be more.It had a range of 1/2 mile and I got this info from a U.K site from a fellow who used them on a British ship.
