More A833 I.D.

Numbers on the pad are not an issue- they are correct dates and VIN number. The issue is the three, 3 1/2", factory painted yellow numbers that appear on the case near the pad. Many have never seen these numbers as they are worn off. Am trying to understand what those three numbers should be and why they don't seem to match what was there. I kick myself for not taking a picture to show you. I am doing a resto, so others who have seen this hopefully can help.
