Re: GT Stromboli Grey ???
Sterling Grey used to be another name for silver on the 156, and I suspect that it was the same on early GTs. Stromboli Grey is a little darker, almost looks like a titanium colour (to me) in sunlight.
Sorry can't be more help, you'll probably need to do a bit more research with the paint code number. Maybe someone on here will have an original sales catalogue listing colour names and numbers.
