Looks like a very handy holder and a quality cover. What was De Vergulde Hand selling in 1554? Shaving soap scented with spices from the Indies? Highly collectible razors? In any case, if The Gilded Hand has been doing business since the 16th century, it has survived some very turbulent times.
Yes quite an sturdy set up. The cover could probably be used as shelter during an bombing.
According to Wikipedia
The soap factory was founded in 1554, making it the oldest surviving soap factory in the world. She passed ownership several times. In 1609 Wijnand Pauw bought the company from Frederick de Vrij. In 1695 Jan Woltman (Johannes Waltman), an emigrant from Lüdinghausen, North Rhine-Westphalia, bought soap factory. After that, the hermitage remained in the family for a long time.
During the 18th century, the number of soap factories in Amsterdam declined rapidly, and after 1812 De vergulde Hand was the last remaining company of this kind. It was then called: Woltman Elpers. In 1920 the name changed to: C.A. Woltman Elpers De Vergulde Hand soap factory.
