I have this holy water font that I estimate might be from the seconf half of the 18th century. It has three hallmarks at the back; they are quite clear, but I have not been able to find anything similar anywhere.
It is quite likely European, but I really cannot place these marks.
The image of the marks is a composition of photos taken with the microscope; the hallmarks are all closely aligned on the back.

Can somebody help to identify the origin? Thank you !!
