This rarity sits in the street where Highland and Wildwood Avenues meet, in Piedmont. Port Chicago was the former town just west of Bay Point where the terrible explosion of 17 July 1944 occurred. The Baypoint Iron Works existed at that time, but I have found no information about it beyond that fact. The town was taken over by the government and demolished in 1968.

Today I found an example in Oakland, at 220 4th Street.
