Pud, I'm thinking foob, but I'm no expert. Rapido has their baggage car in HO in the green scheme carrying one number in the range that CCS is offering - 9193. CCS has CN road numbers 9184 and 9197... which may mean nothing if these were second had cars. Rapido's HO car is a 73' car. This artwork for the CCS car looks like a rather long car, IMO.
There is a shot in the CNR Freight and Passenger Color Guide on page 14, top photo, of CN 9197 in 4/69. Car is a NCS graduate of 1953, 79'-6" long, and clearly equipped with heavyweight trucks (6 axles total). Unless CN re-trucked them with 4 wheel trucks at some point, it's a foob. There are other number series that might be more correct, but not the CN9173-9202 series they are doing.
I bet Mr. Shron will be doing the baggage in N at some point, so patience is likely in order.
