Help identify early top floating stick

I have two tops that came with my early 1950 steel car, one is original to the car the other is from a 1953. Can you help me identify which floating stick is for my 1950? Notice that one curves up right in the middle, the other does not. Thanks

The one that curves up in the middle is for an XK140. The upward curve accommodates a piece of chrome trim on the XK140.

@Mike_Balch thank you

I have had al 3 different versions lazer cut
