If you're talking about the YELLOW-RED combo, I took a picture of that train at 51st Street (Downtown platform). It was car #8609. I think it was on Friday, because that was the day I took the last 3 pictures on the roll before I sent them in to be developed. The other two? A picture of two old signs at Broad Street (Stopping boards (6) and [4\R]), and an M train entering Myrtle Avenue.)
BTW, is that (6) sign @ Broad St a relic of the old days when BMT 67' cars shared tracks with the R types (I know that the [4\R], [6\R],[8\R], and [10\R](Saw one of these @ C.I.) are.), or is it something else?
