Maserati with sunroof or open top.

Hello to all,....I am researching early Maserati's with sunroofs or open tops. I have found 3 cars that were likely installed at the Touring works either before the car was delivered to the customer.

So far I've come across 3, 3500 GT's with period and dated GOLDE (German) sunroofs. Golde was the primier manufacture of 'hard' sunroofs (crank style) in the mid 50's thur 60's.

Maserati factory records are spotty on this, and Cozza has little information. Does anyone have any knowledge, photos or records on early Maserati's with sunroof?

I was told of a 3500 GT shown in the early 60's at the Frankfurt show? Do any photos surive?

There was one 3500 GT located in Califorina 1999, 1 3500 GT in Germany 2006 and one 3500 GTI in Switzerland 1983.

Ciao and best!
