So the Macomb sold on e-Bay in better shape for $26 and $12 shipping. Is it really a little more desirable?Notice that MACOMB looks more like MAOOMB. ^ Interesting thing on it. It is a U-244 "flat top" piece made between 1910 and 1915 by Illinois Electric Porcelain Co. as a dry-press insulator. Source.The dome-portion is gorgeous, in my opinion anyway.But, sadly, mine has damage as is typical of a dug insulator.The inside has a very sharp point in there. ^Then my mom got me this one because it still had the hardware:It is unmarked.And it is somewhat crude-- It is not a perfect circle anywhere on it.This one is not damaged save for two cracks in the glaze.More from its hardware:Nut. Ideas on age and maker?
