Anyone know of the J Day company?
I came home with one of their heavy steel wire gages, nearly identical to this one. Mine goes down to 29 gage.
Did you mean to attach a link or a photo..?

Sorry, guys. This is the similar.
I find some reference to a J. Day company located in Stafford, England in the late 1800's. (Stafford seems to be located just north of Birmingham) But details are pretty sparse.
