Closest I have is July cars/examples from Dearborn. There seems to be some variations through the year so thanks for providing specifically a time period. At least this provides some historical documentation to support a choice
at least these two example are the same or were done by the same worker assigned to that station. Sure doesn't make it IMHO a random application/choice
Sorry for the poor pictures - because of these I labeled the nozzles with green arrows and the clamps/clips with purple arrows
Hope this helps
