Old service stations and gas stations on the National Road in Maryland

The following are a few old gas and service stations on the old National Road, generally Route 40 or MD 144, in Maryland. In addition to the rather distinct architectural style, they can usually be identified by the concrete island in front of the building where the gas pumps would have been.

This one is on the north side of the road, on the east side of Sideling Hill.
  

Also on Sideling Hill, on the south side of the road, a bit farther east.
