The headlight had apparently been mounted to a lot of things in a number of different orientations as evidenced by the number of broken out holes on the bottom of it. I actually harvested it from a Model A Ford 1 ton truck. It is pretty cool and has a brass g-682 tag.
Here's what it looked like at first:
I added a piece of 18 gauge steel to fix the holes and reinforce it for a mount.
I am pretty happy with it so far. It is fixed to the frame so it looks a bit odd when turning as it stays pointed straight ahead. I kinda like that. It is also just strange enough looking on this bike that it begs a second look.
