Put this together as a working draft and looking for some more input from others. Based on research from what I have seen and also talking with the GM/Corvette community and the Mopar community there is some similarities. There were several manufacturers of wheel weights in the USA in the 1960's and 1970's most of which are gone today. What I have seen is three different types of wheel weights being used. Could use some more examples and clear photos so feel free to email me, text me or post photos here. Personally think the best examples today are going to come from original unused spare tires.
I was able to figure out the one manufacturer that made Micro but the Excel and LH was never able to figure out those company names...in case anyone has more information or original boxes with those labels on them.
