1-5-I-N-8.........NORTH AMERICAN AT-6 TEXAN MANIFOLD PRESSURE........Pioneer type D-9 with (19)41 procurement date on face...... std. 3 and 1/8" diameter, Pioneer made high quality instruments and this one is no exception, with super smooth movement, it is about 1" off, but appears in fine working condition, and with calibration/yellow tag, should work for another 60 years........$95
****Here you can see the back seat of a T-6, the MP gauge measured relative work of the engine, and since it was supercharged, it could show when the student was trying to overboost the engine too!**** |

6-3-I-N-8.......LINK TRAINER TACHOMETER....... Not often seen, these otherwise standard looking WWII aircraft instruments have a bright red data plate on the reverse that states "FOR USE ON GROUND INSTRUMENT TRAINER ONLY" ..... and in fact it is a completely different instrument, since it is a pneumatic tachometer! (standard units were direct drive or electric)...... standard 3 and 1/8" face, and made my the well known Square -D company, this is a unique WWII item, designed and used soley in ground trainers.......looks in good condition, and it is still in fine working condition! (just in case you have a link trainer) .......SOLD |
