It can be 1674, 1774, 1874 or 1974 post a picture and I shall identify.
Most likely its 1874 otherwise you can see that it new.
However I have just bought a 1831 piece, seller asumed it to be 1931 due to its perfect condition.
Here you see the 3 towers from 1774
The book contains only marks until 1870 så here you have 1870. Every year had its own different 3 towers so you can see what year from the towers even if the year is not visible.
Unfortunately the book has been sold out and is very difficult to get.
Sometimes the moon is facing left sometimes it faces right. Different stars. Different towers sometimes slim and some times ... and so on.
