That's cool! You really care about tiny details, don't you?
Coincidentally I read a new book called 'Beatstad Eindhoven' (Beat City Eindhoven) last week, which has a whole chapter about the Egmond guitar manufacturers. The factory where those early Egmond guitars (including George's first guitar) were made was less than a mile from the place where I worked until a week ago. I never knew that.
The Egmond family were not such nice people by the way. They were members of the NSB (the Dutch nazi party) during the Second World War and took quite some advantage of the fact that their main rival in the city was a Jewish company.
