Terry,
I suggest a small dental mirror and a flashlight. With some patience and a
careful eye you can see every part of the SB under the plate. I've never met a
piano yet that I couldn't see any part of the board. Takes a while though. My
guess is a hinge screw.

BTW. I use this to check whether the plate is supported well on it's nose bolts.
