I like the cute font that Bendix used here.

This looks like a sweet, solid indicator unit. The knob turns smoothly, and the numbers change from 0 to 360. Entertaining offers on this already great price.

From my dad's vast Arcamex Avionics collection

This Cold War / Vietnam War era Course Indicator MN-97 Omi-Mag was made by Bendix for use in aircraft of the US military and commercial carriers. In military applications of the 1950/60's, this was known as the ID-249A/ARN or ID-249/ARN as used in the AN/ARN-14 Radio Navigational System.  It also was used in the USAF strategic bomber B-52 and the jet fighter F-100 Super Sabre.

According to Flight Magazine dated 1957,

The MN-97 O.M.I. is a combination instrument embodying the functions of an omni-bearing selector, a flight path deviation indicator, an ambiguity indicator, and a relative magnetic heading stabilizer. The RMI requires an additional source of gyro-stabilized magnetic heading information.  The presentation includes a to-from window with sense indication displayed when the aircraft is on or near the selected radial and a vertical pointer for all navigational services. The pointer maintains its center position as long as the aircraft is on VOR or ILS course; a flag alarm indicates "off" when the signal strength is too weak for use. Included on the casing are a knob for course setting and a - Missing - marker beacon indicator light.
