Hack date update: Further review of photos exist of the orange/blue letters on the bay window style caboose class (N22B) as late as 1977, while others of this same class are in the MTA scheme by this date.
This class delivered as N22B #62-70 built by International Railway Car Co. in 1963. Numbered 62 to 7l, featured a bay window for better visibility; unlike N22 and N22A classes (smooth side).
Note: 2 part vertical lube stencils info now called Consolidated Stencils applied are c.1974+ and Hack weather beaten shot, in Sunnyside yard, Marlboro billboard may have been there for 20+ years.
So we are looking at a c.1974-1977 situation. It is in LI City view south toward Chicklets, etc. I place it circa 1975.
