You are bidding on a previously owned but unused N scale car set from a non-layout collector of high quality trains.  This is a PWRS very limited edition set produced by Micro-Trains.  It contains 4 very nicely weathered cars.   This is one of many similar railroad models that came from this amazing collection.

From the Web:

The Canadian Federal government boxcar rehabilitation schemes were undertaken in 1979 and 1980. The floors, nailable door areas, spot welding, and doors were repaired and spray painting was done. A yellow wheat sheaf, a smaller version of the government grain hopper scheme, was applied to the left of the door. Under it was a stenciled a bilingual message, reading in part, "REPAIRED WITH FINANCIAL CONTRIBUTION FROM THE GOVERNMENT OF CANADA".

The way the grain agent would load these cars is a little different from a modern hopper. First the agent would climb into the car with all the materials he would need along with a ladder ( this was very important ). The agent would nail a large piece of cardboard over the door opening from the inside. He would leave a few feet of room at the top open to load the car with. He would then re-enforce the cardboard with metal strapping. This procedure was repeated for the other door as well. Then the agent would use the ladder to climb out of the car through the opening he had left at the top of the door. At the ports a large scoop with a spiked end was rammed through the cardboard door to unload the car. The job was finished by sweeping the remains out of the car.

Loading levels were painted on the inside of the car to tell the agent how much to load to. There are different levels for Oats, Barley, and Wheat as these all weighed different amounts and the car could not exceed a set tonnage.
