Welcome to the site.
The production of the 1960 Golde Top was 2536 or 2500 depending on the sources. It is rare.
There are subtle differences between the press release photo and the actual production roof, notably the attachment of the sunroof headliner to the front of the sunroof.
The roof opening is very wide compared to current sunroofs. It is exactly a meter across (39.37 inches). The roof is of German design, so it is not so surprising that that it is metric in measurement.
