1931 – W. O. Nelson

25 July 2022

2965 Avalon Avenue, Berkeley

This whole block appears to have been paved by W.O. Nelson in 1931.

1930 – H. C. Orth

23 July 2022

3032 Deakin Street, Berkeley

Unlike my other example, this mark has a properly stamped date.

1906 – Peterson & Adler

21 July 2022

2108 Essex Street, Berkeley

One of the nicest marks by Peterson & Adler you’ll ever see.

East Bay Municipal Utility Dist

4 July 2022

Grand Avenue was closed off today for the 4th of July, giving me a chance to inspect the roadway. This classic access cover near Embarcadero appears to be bronze.

Ambo Concrete

11 June 2022

3798 Harrison Street

Ambo Concrete was an outfit run by Sam Sposeto, who may have been related to Angelo Sposeto. I have Ambo marks from two dates, 1976 and 1979. This mark could be any age. I assume W. S. Wayne worked for Ambo.

1933 – Riechel & Bredhoff

26 May 2022

404 Vernon Street

Now I have a high-arch and a low-arch mark from this year.

This house is quite something.

Heating & Lighting Company

20 May 2022

2nd Street at Castro Street

This is a mystery access cover. The site is where Oakland’s original gas works was located, back in the 1800s. As I understand it, they manufactured gas by roasting coal in those days. “H & L Co” stands for “heating and lighting company,” but I expected this to have an “O” for Oakland, like the later Oakland Gas, Light and Heat Company.

The other odd bit about this lid is its scallop design, attested in only one other place, the ancient Sunset Telephone & Telegraph Company lid on 6th Street.
