As Tim said John Smith's site is your best source for identification information. It can be found at the following link: https://fordtractorcollectors.com/identify-my-tractor/tractor-id-history/
Your second source would be to post pictures on this site. The more the better, within reason. A number of the members are very knowledgeable and will help you.
The serial number was hand stamped at the factory and some characters may be very light.
As Tim also said it is basically only good for identifying the block. Many parts may have been changed over the years.
If you are truely fighting rust rather than old paint and oily residue, I would be inclined to try cleaning the flat surfaces with sandpaper and then spraying the actual number with phosphoric acid. That should turn the numbers black. I bought Kleen-Strip Concrete and Metal Etch at Home Depot but I'm sure other's have simular also.
Good Luck!
