Details

Embossing: The U-274 O.P. Co embossed style. The embossing (yes, truly embossed porcelain) is on the top of the upper wire ridge. The O.P. Co marking is for the Ohio Porcelain Company of East Liverpool, Ohio. The company was established circa 1897 and merged with other companies in about 1913 to form General Porcelain Co. The U-274 is shown here

- center insulator of the three. (this was the only photo that I could readily find on-line. If other collectors can add links to OP CO pics, please do)

Location found: Not known to me.

Colors: various shades of brown, and white.


Comments

My purpose of posting this is to see if someone recalls finding these in the wild. Where were these found/used? Why are they so scarce?

Have you ever seen a 274 that wasn't chipped around the edge of the dome? My son, Christoper has two, a white and a brown that both have banged up rims. One theory is that the embossing on the rim made the OP inherently weak and subject to breakage. I have seen specimens that are cracked into at the embossing. It seemed to be the only insulator OP put their brand on and was probably for heavy telegraph which could have increased the damage factor.

The the U-274 does come as a no name too. I think those are attributed to OP Co. As to the time frame for these pieces, I am not sure. I suspect a bit later in their company history. Neat pieces. Jim Colburn By the way, still no answer on where they were found in the wild.
