Hi guys,

I need to know that is, and from what car.
I guess it could be something from the side windows.
It´s 18.7 inches long.

no #'s on it ?

 

It looks like the trim above the windows on a convertible top, similar to the parts on my 55 Ford convertible but not the same.

 

No numbers at all.

 

Could be from a convertible top. Sounds logical to me.

Anyone else an idea ?
