The window was installed in 1986 or 1987. The stamp shows the number "3" followed by "Xi" with the letter "R" in a circle and then the code "85/0".

I am afraid we can't cross-reference those codes to anything. Can you send us photos of all the stamps on the balance box? Sometimes how they are stamped is just as important as what the stamps say. We'll do our best to help from there.
