70's WR tail light

This looks like the same one that was on the late 70's WR's can anyone confirm?

I have found that the CEV 9241 (lens #) comes in two styles - one with a plastic housing and one in metal. The metal housing has CEV stamped on the top, while the plastic has CEV molded in the back. Many Euro street bikes used the metal housing and many of the enduros used the plastic housing. I have been told the WR originally came with a plastic housing.

Pics are of a plastic slant back housing:

Boy that's expensive! Found a square model for the 86 at York for $30. Saw round ones too.

Grouty pointed me to what appears to be an excellent CEV replica for 40 sterling, I'm going to take a chance on that.
