One more observation, look at the triangular depression (outline) on the Engine Number on the 7 in the photo and the rectangular depression on outline on both of the 1 fonts.
I own a Diecast with the exact outlines. These numbers have really deep strikes, and let you see the shape of the die tooling used for the numbers
I found it interesting.

I also notice that the E and - are both in the same matrix...
I think Honda used this font for all its production because I had two small coupe Honda S800 (fantastic!!) and the numbers of police were identical to the chassis and engine ...
