This is a DRC, a direct reading compass, it's a compass card suspended in a mineral or alcohol based liquid in a bowl, with a means of trailing wires to dampen or act as a brakeing system and with magnets to reduce the moment of inertia (which keeps mass to a minimum)....it's a clever simple little thing that stops the card and helps it to settle down after a turn and to not spin like a top and hunt for north at an inertial rate.
Not many people know this but inside these you have a sapphire cup, on which a iridium tipped pivot balances......buy them all up now for the jewel's
I'm told this one comes from an Me 109, it was sold to me for 12 pounds by the ex RAF transporter driver who picked up the reminents of downed AC in the UK during the Battle of Britain period......he was then sent to Africa. Where upon they were sent to recover their own AC more than any enemy AC.
The instrument is dated October '39 (10 39) it's an F.K 5, model number: F.1 2.3 2 1.1; anyone out there know what type/s of AC would have used this compass ?
Kind regards,
Marcus
