Here is a variation you don't see everyday. A typical CD 134 Diamond "P" measures in at 3-7/8" T X 2-7/8" W as noted in the current Price Guide. Here is a variant of the CD 134 which measures 4-3/16" T X 2-7/8" W Please note a recent posting in the Collectors Album by Roger & Beth Ziesak ( Oct. 20th 2013 ) of a similar variant CD 134 [listed as CD 134.4] with no embossing .[id=386871526] Both insulators, embossed and unembossed are Pennycuick style. Truly an unusual variant for the CD 134. Maybe a new EIN # is warranted?
