I am very inclined to believe that this stamp – on the west side of North Clemens Avenue between Jerome and Vine – is from the same contractor responsible for one of the blog’s early mysteries, the odd string of letters and numbers I first found on Kalamazoo Street and then later encountered versions of in a few different places. The first one looks a bit like “DAY02” but with no spacing and odd-looking characters I wasn’t sure it was a name and date or just a code of some kind. If this is the same contractor, then this is proof that is a name and date.
The case is still not settled. The first one I found had a pretty unambiguous D as the first letter. But then a later one, which otherwise bears a strong similarity to the first, is definitely a B (“BAY03”). A third one looks like it is readable either as a D or a B.
And what about this one? The style is very different from those odd mystery stamps, but the “D/BAY” and two-digit date makes it hard to resist making a connection between them. The (regrettably faint) first letter first appeared to me as a D, but on closer inspection, looks to be a B after all, and that’s what I will go with. I believe there is another one like this on Fairview, but it’s as faint or fainter. I will have to get a look at both of them at a few different times of day and see if my appraisal changes.
