Looking for some F1 cars

I'm wondering if there are any 50s and early 60s F1 mods. Two particular cars I want are the 1954 Mercedes w196 streamliner, and the 1961 shark nose Ferrari do any of these exist, or are there any other cars from this era available

 

While both would be great to drive, nothing has been created or converted.

 

The "sharknose" was worked on a long time ago by Zonder but never reached a finished level
