Yesterday I walked into the antique store in my town where I have had come across some good finds, and they had once again another box of insulators! Well the first thing that caught me eye was the dry-spot in mint condition. I could not read much of the embossing, so I searched online. I found that it was a U-188 Square-D with [F-Skirt] AE Co INC/ Chicago, Ill [R-Skirt] Pat Pendg. I found they are worth about 7 bucks, so I am happy with what I payed. I have no idea what the other one is. I think it may be Italian. On the top of the "saddle groove" it has 2601 K and IFO 58. Any info as to value, and origin would be appreciated!
