Hi Tom, welcome to the forum,
Looking at your images, I believe we could call those 'look alike apostle spoons', the marks are; pseudo marks, to imitate the older Dutch city guild marks, thus pretending to be antique spoons and to look old.
I would like to see a close up of the R82 rectangle mark, could you also check for other marks, like a little sword mark.
For information about Dutch hallmarks and older Dutch city guild marks see:
