Are you perhaps thinking of RK05 cartridges? ?Those have visible
notches on the hub and come in 12-sector versions.. and
16-sector versions
Here are the photos from the auction

Ah, gotcha. With 40 being such a large amount over 12, I had
incorrectly guessed you were looking at a different picture.
picture "data02" and "data04" have
the hub in view. ?Way more than either 12
or 16 sectors. ?The 40 mentioned elsewhere in your reply, but not for RL02
seems to fit, but I'm not sure I can count how many notches are there.
I counted 40 from data4.jpg (and I said 40 for both RL01 and RL02 but
perhaps my statement was insufficiently unambiguous - those drives
have different numbers of *tracks* but the identical number of sectors
per track).
