For the GTC 300SL.
Now, I typically don't tend to do many 50's liveries for a couple reasons; for one, it's hard to get good photographs of non-championship 50's races, or many angles on certain cars. On top of that, the liveries are often quite plain, so a little less enjoyable for me to put together.
But exceptions can be made, of course. The Jaguar D-Type for instance, my all-time favourite Jaguar. And the 300SL, the prettiest Mercedes of all time (in my opinion).
This one was ran at the 1955 Watkins Glen "Glen Trophy" Grand Prix, where Ed Hugus drove it to 2nd place overall after starting in 16th. I only found one photo of the car, so I don't know what the front looks like.
