Radiator Overflow Hose Clip

[cook_dw]

While going through some recent purchased parts I have run across several radiator overflow hose clip codes. I would like to see if I can collect data points in this thread to verify if there is any correlation or if it is some type of date or ??? Unless someone has info on this topic it would be greatly appreciated. Thanks.
