Always wanted a really nice Jumbo but didn't want to put a couple of hundred dollars or more into one that had some sort of damage? How about one with all the bells and whistles and in super condition! Skirt embossed JUMBO .....on the reverse side of the skirt PATD JUNE17, 1890, AUG19, 1890 and base embossed OAKMAN M'F'G CO. BOSTON . I'm sure not going to tell you this insulator is mint, but I will say that you will be hard pressed to find one in better condition. I see a lot of blue in the color but you be the judge. My price, including shipping and insurance is $450.
