Searching for a picture

[Craig Lewis]

I'm working on a 31 coupe cowl and hoped someone could help me with a closeup photo of the stamped detent in front of the cowl light hole?
It seems that some cars have a smooth stamping...while others have a "raised bubble" in the centre of the stamping.
(Still trying to determine when the change took place)

Below are pictures of the 2 designs.

*I need a closeup of the "raised bubble" design if anyone can help.
Thanks in advance.

Anyone? Leads to an online pic maybe?
Thanks.

This what it looks like in my 1930 Coupe

Thanks for that Bill. Yours has the smooth even indent I see, as opposed to the bubbled indent.
Perhaps the bubble was only in 1930?

Anybody else out there who can help with a closeup photo of the bubbled indent or info when/why it was done?
Here's the best picture I have(again) showing the outward bubble in the indent. The bubble is faintly visible at bottom left of this pic.
