I don't know what that is, but it's not an MSV11-R. Here:

Alas, there is almost zilch original DEC documentation extant which speaks of
it; not even uNote #28:
which briefly covers all the other late DEC QBUS memories (including the
MSV11-M, which ia otherwise _completely_ un-documented) mentions it.
But I agree that given the 18 chips, it'a probably parity.
