Is this a Phillips 66 Station? I note that it has tip-out glass, like Phillips. And next to the tilt-out glass, the little multi-slatted louvre-style window, just like Phillips stations.
There are a few of these designs, with a single garage bay on two perpendicular sides, probably designed for corner lots.
The rectangular canopy is newer, of course. I could imagine this having the Phillips "Gull-Wing" canopies, and a different roof.
If it's something else, help me out, and I'll change it.
