1940 LaSalle Fender Turn Signal Glass Lens OEM. These are OEM they have as you can see in the photo's the Guide number 924836.
On the other side bottom' is LL CO 2210. They came partially frosted on the inside from the factory.However I do not know if the color difference denotes right and left or if the color of one lens just faded or was removed. I will leave as found however it seems to me the color could be removed or added to the other to match.
As you can see in the photo's there is a couple of minute stress cracks around the hole. I asked around, was told most of them have this. Was also told these are super rare.
Length on bottom, back to tip. Width measured on the bottom 1 11/16 at the widest point, it is slightly tapered. The base is slightly concave so as it sits flat on a desk 1 3/8.
