Ted, the picture for F&C Kit #6600 is lettered for NYC gondola #399574. It corresponds to NYCL lot 528-G
built in 1926 by G.A.C Co in East Chicago. The NYC General Arrangement Drawing for this gondola is
#Q-38634 and it shows these Gondolas as having a brake wheel type of brake. In addition Wayner's
book "New York Central Cars" shows CCC&St.L gondola #72111 (lot 508-G), another High Side Drop
Bottom 110000 lb. Gondola, covered by the same drawing with a brake wheel. Hope this helps,
sorry for the delay in answering.
