Great work Noir Noir, I think you have this one.....the San Mateo County list of remediated environmental properties shows a LUST (Leaking Underground Storage Tank) site at 6417 Mission St., just south of Hillside Blvd. and very near the billiards parlor at 6375 Mission St.....this would put the station right around the fenced area in your Google street view....








Starting in about 1980 there was a nationwide effort to clean gas station sites, even if the station was long gone, as the metal underground tanks of prior generations invariably corroded over time and leaked petroleum products into the soil....note the action to clean the subject site commenced in 1986.

Here's a view facing south and towards the fenced site at the corner of Hillside and Mission, note the DC Smoke Shop building which now has an address of 6389 Mission St....





....the siding looks similar to that of the billiards parlor.....





I could not find a zoomable 1930-ish aerial of the area, that could put the matter to rest.
