I recently found this Hudson at a local antique co-op for only $48 including a 663 aluminum observation car. After a bit of cleaning and oiling it runs and smokes great. However at some point it was relettered and renumbered and I would like to use reproduction decals to return it to it's original appearance. It has the smoke unit in the boiler, air chime whistle and a knuckle coupler. What would be the correct number for this version?
Thanks for any info.
