I bought this single bit at an old antique warehouse in NH a few years ago and finally got around to cleaning off the rust. There is a faint stamp that once said OAKLAND ME, it's a little easier to make out in person. Trying to figure out who the manufacturer was. The only other mark is the weight stamp on the bottom of the poll (3 1/2), which I've never seen in that location before... is this a distinct place for the stamp? Came across something suggesting Spiller but I'm not sure how reliable that information is. Let me know any thoughts!
