WW II US Navy – MARK I RANGING INDICATOR – Anti-Aircraft Artillery – NICE!


1 in stock


You are bidding on a VERY NICE used example of a WW2 US Navy  Pioneer Mark VIII Magnetic Compass, as used ONLY in the cockpit of the SBD Dauntless and TBM/TBF Avenger aircraft! 


The Mark 1 Ranging Indicator is a hand held finder used to ascertain the range of an enemy aircraft based upon its known wingspan. They were only as accurate as the observers knowledge of aircraft identification and of course, how rapidly he could spot, identify, track and calculate the information to pass this on to the gunners (usually manning 20mm to 40mm guns or a 3″ gun mount typically used on auxiliary ships and small craft. i.e. PT boats, LCT/LCI, PC’s, etc). The observer held the indicator about two feet from his eye, measured the wingspan of the aircraft between the two wires in the center viewfinder, which widened or narrowed as the interior metal ring is rotated, and then read off the estimated range to the gun captain.

The problem with using this indicator was not only identifying the aircraft, but measuring the wingspan as the aircraft changed its angles of approach. Some enemy aircraft were easily identified due to their distinctive shape and engine placement, while others were more difficult to ID, especially when moving 300 to 400 MPH & the observer was standing upon a pitching deck with guns banging all around. Still, better than having no aids at all. It was located on both the pilot and co-pilot instrument panels.

 Made of plastic and steel, this instrument is in EXCELLENT used condition!  Features numerous aircraft types printed on the face.  Dated 1944, it still retains most of its original finish (some very light scratches)!  Data label is complete, and clearly indicates the model, type, and manufacture.  An EXCELLENT addition to any collection, display, or restoration project!
