Francis Barker M-72 Prismatic Compass

Price $260.00 Sale

A rare Francis Barker M-72 liquid filled military prismatic compass. This is the military MILS version. The Francis Barker M-72 Prismatic Marching compass was a direct descendant of the legendary MK III that was in use throughout the second world war. Produced in the UK in 1972, it was a development of the M-71 which was introduced in 1971 and was one of the last Barker compasses to feature a mother of pearl card. The M-72 was only made during 1972, in very limited quantities, before being replaced by the M-73 in 1973. The M-73 remains in production today, is still regarded as the world's finest liquid prismatic compass, and is standard military issue with many armed forces.

The M-72 was very similar to the M-71, with a brass case and lid. Most of the M-71 and M-72 compasses were totally unmarked, some had 'Pat. Appd. For' engraved on the base, like this one. Almost all of the M-72 compasses were exported to Australia. (Further details of the M-72 can be found at Paul Crespel’s excellent website:


The compass is in good condition, in full working order, and finds North very well. There are no bubbles in the fluid. There is some  wear to the black paint finish of the brass case. The lid hinge is a little stiff, but strong and fully working. The glass and compass card are in very good condition. The compass is calibrated in MILS. The original night lights have now expired and would need to be renewed (only really necessary if the compass was to be used in total darkness).

Dimensions : 85mm x 60mm x 34mm
