I have been seeing Show & Tell postings for insulators on here, and that made me remember I have a collection that were my father's (he passed away in 1997). I went to the basement and found some that he stored in a wooden box. I do not know anything about what's what when it comes to insulators so if anyone wants to educate me on the insulators in this collection that would be appreciated. The ones that are not glass do not have markings that I can find. The six made of glass have marks as follows (I am leaving out writing such as "Made in the USA"):
