A vintage Silva Type 5 Induction Damped compass, made in Sweden, dating from the mid 20th century, probably c.1960's. With a rotating aluminium bezel, and transparent baseplate. The compass has a red/white needle, and bearing markers on the base of the compass capsule. The compass comes with a military style webbing pouch.
The first Silva Induction Damped compasses were produced in 1946. Magnetic induction damping occcurs when the needle is moving within a copper housing - in this case, a copper band lining the aluminium bezel. Induction damping is an alternative to the more common fluid damping system, and was used by the U.S. Army in its M-1950 type military compasses. The main advantage of induction damping over fluid damping is that it is considered to perform better in extreme temperatures.
Condition:
In very good condition, full working order, and finds North very well. The bezel rotates smoothly. The webbing pouch is in very good condition.
