Nanchang CJ6A Turn and Bank
Anybody know what the markings on the original instrument turn needle mean. What is the significance of the 45 at each end of the arc and what do the 3 white hash marks next to the center mark signify ?

It's EUP-53, the same turn indicator as on the original Yak (or, more likely, its Chinese replica). 45 means the rate of turn corresponding to a 45° bank angle coordinated turn. The smaller marks correspond to 15° and 30° bank angle, respectively. 500 is the speed (in km/h) at which the instrument is calibrated (yes, I know CJ-6A doesn't fly that fast).
