Case Xx Dot

I have a Case XX pocket knife with 11 dots on the blade. What does that mean?

It is an old knife. I found it on the riverbank over 30 years ago.

the dots are a age determinations, as such with case knives, each decade they change their number patterns, some have dots, some have .x.x.x. some have the c in case high lit-ed. but if you go to www.case.com. and look it will explain all the factors of the dots etc.
