Park Boulevard and 8th Avenue

The Oil Marketing Equipment Company was at 325 Fremont Street, San Francisco. It was run by an Atherton resident named Frank D. Mahoney. You could phone him at GArfield 1-5328.

The 1948 San Francisco directory lists it as “Manufacturers and Distributors of Specialized Equipment for the Oil Industry.” Its factory was at Dollar and Linden Streets in South San Francisco, on the railroad tracks. As of 1960, its factory was in Redwood City at 3524 Haven Avenue. It was listed in the San Francisco directory until 1962. All of those addresses are occupied by newer buildings today.

1925 – N. Lena

575 Merritt Avenue

With this find, I’m missing only two dates between 1920 and 1934.

Golden Bay Const. Inc.

5 March 2019

10 10th Street

You may recognize this address as the Oakland Civic Auditorium. The stamp is at the end next to the museum.

1921 – F. A. Mero

3 March 2019

1257 65th Street

Whereas my other example of F. A. Mero’s mark is straight text, this pair, in the same neighborhood, displays two different versions of arched text. I’m guessing that Mero struck one character at a time.

2015 – Rosas Brothers

2 March 2019

Two versions of that year’s stamp:


Lee Street at Monticello Avenue


307 Jayne Avenue

I’m not sure how this happens.

(This was previously stuck at the end of the S. Aiassa profile)

1929 – Ed Doty

2 March 2019

1117 Alice Street

Unlike my other example from this year, this stamp contains the day and month on a separate line.

1922 – J. B. Castellotti

26 January 2019

2700 block San Pablo Avenue

I’ve recorded a 1922 Castellotti mark before, but this one features the month as well as the year.
