1927 – Sorensen Bros.

2 October 2024

819 Paramount Road

I finally deciphered this one. The “27” could still be the day of the month, though. Short of a lidar scan it’s the best I can do.

AC Transit

26 August 2024

1600 Franklin Street

This access cover sits right outside the big AC Transit headquarters building, where it protects the fiber optic connections. I’ve passed over it for years, but today I noticed that the two S’s on the lid are backwards. The manufacturer responsible for the error, Alhambra Foundry Co. Ltd., was founded in Southern California in 1923, but after a century’s existence was swallowed up in 2022 as part of a relentless acquisition drive by the private multinational metalworking firm EJ Group. Alhambra’s shortcomings are also evident in the firm’s former website, preserved on archive.org.

1929 – Frank Salamid

13 August 2024

1321 Acton Street, Berkeley

Frank Salamid, sidewalk maker of endless variety, stamped the date day-first in May and month-first in December.

1921 – Schnoor Bros.

11 August 2024

1211 Curtis Street, Berkeley

This whole block is full of 1922 stamps and this one exception.

1914 – The Oakland Paving Co.

9 August 2024

4317 Salem Street, Emeryville

A fine, crisp example from this year, including the union bug.

1927 – Lee J. Immel

18 July 2024

1201 Evelyn Avenue, Berkeley

This is only the second dated mark by Immel I’ve found.

1921 – J. H. Green

16 July 2024

1337 Santa Fe Avenue, Berkeley

A dated example of Jesse Green‘s stamp.
