I had a fellow collector friend in Alberta that thought you could figure out how rare or common something was based on how high the serial number was. The trouble with that is how do you know what number they started with in the first place? How do you know that maybe the low serial number wasn't just the result of your radio being from an early production run. As for sharing cabinets among models Canadian Westinghouse used to be notorious for that, one set that I have is a five tube AC model but they had a seven tube farm set that used the same cabinet, the same is true of the Westinghouse used in "A Christmas Story" they used a few different chassis in that cabinet and in other cabinets.
