Jim, speaking again mostly from my knowledge of the 11th series, I don't believe there is any correlation between frame#, steeing gear#, and engine#, other than the former two numbers being within the same general numeric range as the engine#. Engine number, vehicle number, and thief-proof number don't have a numeric correlation to each other but were recorded by the factory and retained by them and the dealer and probably the branch in the form of the Vehicle Unit Record Cards as discussed in my articles on the thief-proof numbers. There may have been other records as well, still lost to time.

Based on my knowledge of the 34 cars (and I don't know how far this can be extended in either direction), if any of the three (engine, frame & steering gear numbers) happened to match, it would be sheer coincidence. An exception perhaps, if the sale was a chassis only for full custom coachwork, the vehicle number often appears on the frame, for example 1107-21 as both a VN and chassis#, would be the 11th 1107 chassis-only. The same situation has been observed on a couple of those few junior cars sold as a chassis-only for full custom coachwork.
