911 engine w/ carbs image outline history
 

Hi everyone. I started a similar thread today but wanted to move it here. What is the history of the engine image below?

One fellow Pelican mentioned this was made before the R Gruppe logo. This one looks similar.

I would really like to get some basic monotone / grayscale metal grill badges made like the first image without the wording. Is this image copyrighted? Does anyone have a high quality vector image?

Thanks,

Scott
