who has photos of 1909-10 and 1911-12 brackets.
Here are a few photo's
notice the bend rather than a swing where it bends, Bob
Here's a 1911 style, notice the parting line on the side of the bracket.
My 09 frame has brackets with the parting lines on vertical part of the stamping from what I can see. in other words the 09 was stamped from the side and 11/12 from the top and bottom. Does anyone else have that same observation?
