I haven’t sighted a Frank Cizek mark in quite a while.

C. A. Heldt is a new maker for me.
1945 – C. Valenzuela

3505 E. 16th Street
A very nice date from C. Valenzuela using all four digits.
1930 – J. Widel

Glascock Street at Peterson Street
This curb-cut mark is conceivably by HB Parkco, of Hayward, in connection with the revamping of Glascock and construction of the new waterfront walkway. Whatever—I’m always glad to see a mark from the current year.
1986 – Davis & Sons Inc.
13 December 2011
707 37th Avenue
This forlorn little block, where you take your electronics recycling, has a pristine version of the 1986 Davis mark I’ve documented previously. In fact, it differs from the other in having two dots flanking the date.
