I know Straman made a few, additionally, I know that some where done by an unknown (by me source) as there was a black one spotted in Monaco one year but it had a full height windshield so it wasn't a Barachetta either. My thought was perhaps it was a Sultan special but I haven't heard anything else about it.

 

That is a beautiful and unusual car.

It has been for sale for over a year, however!

 

It is with a hard-top construction like the Mercedes SL.

Clearly not.

The second car is the Sultan of Brunei car which is like a 500SL but most likely Pininfarina built.

The first car and the subject of this thread is Stramman built car.
