Paul, actually 2 A-B FT sets were sold, 806 & 807 went to the B&O in the spring of 1957. They were the only ones to sell, The book also has pictures of the NW-2's working on the NYC ie O&W paint. There is also a picture of EL F3 7144, in the black and yellow scheme in the book. The FT's lasted until mid 1966 so anyone modeling that era needs 8 sets in the yard.
