OVERLANDFLYER: the 765 got its Mars light reinstalled in August 2016 (in conjunction with the commemorative NKP 767 renumbering) and has carried it since then. The FWRHS Board intends for the Mars light to remain in place indefinitely.
Addressing some other details in this thread, the NKP 765 spent the first half of its NKP career WITHOUT a Mars light (1944 to 1951) and the second half of its NKP regular service career WITH a Mars light (1951 to 1958). No surprise that BY FAR, most photographs of NKP Berkshires were taken during their last year or two as other railroads dieselized and the NKP was one of the few still running steam.
Note that a "flag box" has been restored to the front of the 765 this winter. They were standard issue on the Berkshires but the original was rusted out and the lid was mashed out of of shape by crew men using it as a step. It was cut off during the first overhaul and finally got replaced. The NKP used "metal flags" on their locomotives and cabooses, in place of cloth flags.
