PB Tail Light

[Canadian PB Kid]

I've been trying to decipher on what tail light came on the Canadian PB sport roadster, The parts book list some but by part number, it's hard to tell what it looked like. The only original pictures that I could find are in the accessory section of the parts book. I searched this forum and came up with a few possibilities and most lean towards the lower one in my picture.

Then last month I was reading our local old auto magazine and they had this quiz, would number 5 indicate that tail lights with reflectors were not available on any other earlier vehicles prior to 1933?

These are the three I have rounded up so far, left one is the only one without reflector lens, it came in a box with the car, the one one the right was on the car.

 

Any thoughts?

The lens and ring at the bottom of the picture matches my sport roadster.  And the dovetail in the background is something I am looking for.
