There does seem to be a slight difference between the two stamps...in the smaller photos they look pretty good. Does anyone have photos showing similar stamps from that time period for a comparison?? I always thought there would be a slight difference in appearance based on the stamps and the two different metals...but the numerals should be the same size.
I guess I'll have to take my own advice and look at one of our cars....but, not today.
Great detectives on the SYC...that's why I always tell folks you have to see it in person.
