Unusual rear light lens for sale on fleabay...

I've not seen one of these before.
Don't know if it's of interest to anyone; claims to be for a Minor, but I'm doubtful of that.

It is an aftermarket one, I have a few of the L471 lenses made by Britax and other firms. The reflector in this one will not be adjustable, as there is no reason to do so, but rather turns around in its slot due to the way it is fitted.
