Recently purchased a Purol Arrow logo sign. The manufacturer is somewhat blurred (lower right corner) - "American Bldg, Chi,
Balto. Eml., & N?Y Co., Md?". Probably something to do with Baltimore Enamel, NY.. I did determine that Pure Oil Co was located, at least for a period of time, in the American Bldg in Chicago.
The sign is blue in color, measures 70" x 18", right pointing arrow, Purol in large letters, with "product of Pure Oil, co,
U S A on right side of sign....sorry unable to a pic.
I located pictures of a Purol pump plate and a similar sized Triolene Arrow sign but not this particular sign
Any info re this sign will be appreciated..Thanks
