I have a #76 and it is definetly a 1863, but when I looked closely it looks like the 3 is slighty different than the other numbers. It is the same size as the 1, but smaller than the 8 & 6, with the 8 being slightly larger than the 6. Also either the 3 is etched deeper than the other numbers, or it has a darker color because it stands out more than the others. I also have a #2190 Malaysian with no rod in storage, and I will try and find it to see what differences it has.
