J. G. Jackson notes that this was the business office of the Wrightsville Lumber Company.
Mr. Jackson also notes that the pumps were used to fill the operators’ trucks and not for use by the general public. In researching the pumps, I ran into a bit of difficulty regarding the one seen below. There are numerous references to Shell’s earlier Diesoline brand, but I could find nothing about Dieseline. It was probably Shell’s attempt at reviving an earlier brand.
