A good example of a 1700s chest.
In my previous post i posted a link to the national museum from the Netherlands. The box lockcover is almost identical to mine (except for the fact mine is actually still in one piece

).
The source on this cover tell it was abandoned by Dutch setlers from Nova Zembla (africa) in 1596 (!!!!). A English captain found the chest in this condition in 1876.
Only diifference is the size. mine is 40x39x81cm and the on the museum is around 32X33X69 cm.
