Ah, right you are - brain fade, late at night.
I went looking in my BA11-K collection, and found a couple that do have the
rotate - the part that bolts to the box has a huge 3/4 circular plate, and a
metal strip that runs to the front of the box with a huge (~3") handle bar at
the front, which releases it to turn.
I have this bit set that the outer slides (the parts that bolt to the 19"
rack) are the same for the rotating inners, and the non-rotating ones (as
used on, e.g., the RK05 and the BA11-F).

I went and had a look at some, but there is no name, or number, anywhere on
them.
BTW, these also rotate.

It's sad and too late now but a few years ago when I was leaving the old house
I couldn't give that stuff away. I had 4 complete sets of rails for BA-11's
that
went to the recycler because I couldn't find anyone to take them. Also a bunch
of those funny rails for RL drives.
