There are pictures of both locomotives in those schemes on page 77 of R. Craig Rutherford's "Alco's FA, Running in the Shadow". 366 does appear to be black; and 369 is a light color, possibly grey.

I need help finding pictures of L&N FA2 unit number 366 and 369. What I'm looking for are pictures when these units were painted with the 3 diamonds on the front of the locomotives. From my understanding 366 was paint black and 369 was painted gray. I have found a couple pictures of 366 but there not to plan. I have asked around in different groups but some didn't know they existed. Would anyone know where I could find pictures of these units at? Thank you for any help.
