It is easy to notice that the finder as it comes sits very loosely in the accessory shoes of the Soviet RFs. Maybe it is a common wisdom, but to the moment I used pieces of cardboard to keep it in place, and didn't realize that the cut tabs on the finder's foot are intended to be bent down until it sits in a shoe tightly.
Posting this in case that anyone else here is as clueless as I was yet.
