Well, it looks like for 1992 Mitsubishi requested to keep costs down for whatever reason.
Steve, you could probably correct me on this, but I'd almost say that there isn't any 'indentation' on the 1992 numberings in the center at all? I can clearly see that the surface of the metal was impacted on the 1991. If you feel the center area, you should be able to feel the 1991 engraving.
After a little bit of research, it would appear that it's a Double Line Roman font. I don't recall exactly how to measure the font sizes, but if you have a ruler with .1 increments (not 1/2, 1/4, 1/8, 1/16), measure the height of the 0. Whatever that turns out to be, like .12", then it'll be size 12 font.
