The original 65/66 examples that I have seen had the specific gravity written in pen or pencil, the date stamped in ink, and the inspector written in pen, ink-stamped, or punched out.
The problem is that the original decal was paper, so it's life expectancy was pretty short. If you want to be more correct, order the ECS version that NPD sells and fill it out. It is a nice version of the original decal.
