Don't have a date when the Linco Station was opened.
Would have been in the late 1920's.
I will see if I can find out.

The Ohio Oil bought Linco in 1924. At that time Linco stations were primarily located in western Indiana and Eastern Illinois near their refinery in Robinson.
The Ohio expanded those into Ohio and Michigan.

I know that on September 1, 1939 The Ohio ceased using the name Linco, and renamed their stations Marathon, which of course they got from the purchase of Transcontinental Oil in 1930.
