Mechanoinstruction scraps

[Gummel]

Some have noticed they don't stack. I identified the ones not stacking, and they are different. The 4 I have identified so far are:
...fi.....io.
.......y.o..
......ur.t...
..c.a....b...

There is a clockwork named Bellfast who is looking for a complete tablet of these.
I will refrain from speculating as that is against the rules of these threads.
