Default Model A lock washers

I just had a bunch of stuff cad plated. While sorting everything out I got to looking at my lock washers. Most are serated on the outside edge similar to a dime. many others are serated with various patterns mostly on the outside edge but sometimes on the inside edge and sometimes on the face. Are they all Model A or are some from different cars? Also, are lockwashers judged in the blue ribbon class?
