A 1946 Hudson would have New York Central on the tender without the oval logo. It would also have a 1946 thin shank coupler. Also the engine is a SIT design. Gilbert changed to a smoke/choo choo unit in the boiler in 1948.
Couplers progressed as follows. 1946, thin shank, no weight. 1947, thick shank, no weight. 1948, thick shank, brass weights. 1949 to end of link coupler production, thick shank, black weights.
Many set numbers continued unchanged from 1946 through 1949. An "A" was added to the carry over set numbers in 1948.
