The open stud versions should be alternates (or regular parts in this case) but
I'm not going to approve your requests to remove the blocked open stud versions.
They were added by Jean (bje) instead of undetermined entries and I don't
think he submitted his requests without good evidence. Also this service pack
was available through 1992 and at that time (1992) the blocked open stud version
was the normal variant
(here is a set with blocked open stud and 1x1 round plates still on sprue, so
it must be from 1992 or earlier: https://www.bricklink.com/messageThread.asp?ID=241824
