C. Valenzuela abandoned the doubled-up version of his mark (which he’d used since his debut in 1938) after 1960, and he also stopped using properly stamped dates after 1959. So this example from 1953 with its hand-drawn date can be seen as a harbinger of his decline.

This extends Hennig’s range another year into the 1940s.

I’m getting a pretty full set of these going from 1924 to 1942.

This is about as clear as C. L. Rogers marks get.

This example of Aaron Dahlquist’s 1931 mark used large digits for the month and year.
Now I need to reinspect all of Oakland’s sidewalks to document these variants.

It turns out that Aaron Dahlquist had several variants of his mark. My previous example used small digits for the month and large digits for the year. This one is all small.

Like every L. M. Williams mark I’ve seen, this is lightly made and hard to read. Perhaps he was shy; perhaps he just waited too long before applying his mark. This one is a double strike.
