I bought these today. They are neat.
These were cataloged in 1957 only. The Canadian Pacific F3s come in the brown and gray scheme shown here usually being brown paint on gray molds, but some rare versions have both the gray and brown are painted on orange molds.
The decals on the nose are almost always damaged. They are applied over the voids for steps and door details and just don't survive being touched. The decals below are a little better than usual.
Also, many of these locos are found with the nose cracked at the light. This happens because the worker who put the lens in pushed it in to hard, and after years of stress, it cracks.
The Canadian Pacific 2373 was sold only in an AA unit like the one shown here.
These are later units so they have the portholes filled in and the louvered roof vents along with armature type couplers.
The powered unit has two motors and a horn. The dummy unit has only a light.
This is a very powerful loco. It was sold in sets with 3 aluminum vista domes and an observation. Two passenger cars were available separately to make a five car set.
Here's a video of the loco pulling the cars from the Santa Fe set. The horn works well.
