Vallejo Paint - Model Railroader Magazine

Bill, I think Lantz's over in Horseheads had a few bottles of dark green left in stock when I stopped in last week.  It might be worth a call or a drive to check it out.  Also, there may be a Federal Standard (FS) number on the bottle you have on hand.  With that, you should be able to cross-reference other brands of paint and come up with something close, if not an exact match.  IMO, Tru-Color REA Green is close to the green the Lackawanna used on some of its trailers, so that might be worth exploring.  

Edit:  I don't know if anyone in the Triple Cities carries Vallejo, but the Hobby Lobby in Horseheads has some of their colors.  As someone mentioned, you can mail order Vallejo products (this is where those FS numbers come in handy).

Good luck!
