I live for the CABE
I had wondered that too, but also looking at the top the rear triangle, it has a a more “pinched off” A shape to it. I’m not very familiar with Iver Johnsons, but I feel like I’ve seen some with that arrangement. Not sure on the head tube though.Was going to say it looks like a repaired/replaced head tube. From the pic inside of head tube looks a little new. A look at the rear welds and font/layout of the serial would help
