Rumsey Street is the “other Allen,” what Allen is called north of Michigan Aveue. For some reason, a lot of the streets between Clemens and Pennsylvania change names as they cross Michigan or don’t make it across at all. Things get a lot more regular from Clemens on east.

This slab is on the west side of Rumsey between Vine and Jerome. I read it as “C & F Const Co” but I can’t find any information about a business by that name in that time period. Interestingly, there are several other 1960 slabs on Rumsey but they instead come from the equally mysterious Gossett company. Encountering them on tonight’s walk did give me the chance to see some clearer examples of Gossett stamps and from them I am leaning toward “C. Gossett” rather than “O. Gossett” as the correct name.

Update 9/19/20: I can confirm that it is “C & F” as I have found several other like it (but clearer) on Fairview Avenue just north of Michigan.
