Happy St. Patrick's Day! Here are 3 of my many other rather common insulators. I'm posting these ones because i have questions about each of them, and hoping that someone here has answers.
1. Emerald green insulator marked Brookfield New York has what looks like D1 on top. What is it? Why does it look like it was applied by hand vs. molded as i think most of them are? What does that mean?
2. White porcelain insulator- marked H A105- what company is it? Unfortunately i wasn't able to find much about it.
3. Brown porcelain insulator- unmarked- is a mystery. I see a few similar ones on ebay and they are also unmarked. Any idea what they are, how old, etc?
