These came out of an old building in Denver ages ago. Insulators are original to the brackets. One is a 134 KCGW (clean chip on skirt) in a greenish aqua and old cloth covered wiring attached. Next is a 162 R Good (dot on back) in blue aqua (couple flakes here and there). Each bracket is somewhat rusty but also too each has some old tarp like covering on the threads. They are cool! PP fine but use the gift option please. $40 each and that includes postage. Buy the pair and $70 total with postage. US Addresses. Thanks!
