Harbor 1951, 1969 maps. Union 76 subsidiary brand.
Someone told me they were sold to Fina in or around 1970,
do not know for sure. Do know they are no longer with us.

Small Harbor logo. Not sure who sent this.
This is actually unrelated to the Harbor Refining Company in California.
It is the logo for a short-lived Champlin off brand used in the
midwest for a few years during the mid-sixties.
