Pin records


Digging through my old club zine, I found a quarterpin by
our old chairman and problem specialist Szameitat.
I did some more digging:
- This is no total quarterpin, "just" a #4 where three
pieces are deflected.
- A total quarterpin is f9542 by Smits, but using G and N.
- A 1/6-pin would be possible in theory.
- An orthodox total 1/3-pin surely exists since long.
(P1022157? Didn't check completeness...)

So, do you know...
- orthodox quarterpins with more than one thematic variant
- an orthodox 1/6-pin
- helpwise, a fairy 1/6-pin?

Oldest 1/3rd pin I could find is from 1882:

THX for the finds. The 1/3-pin is total; but not perfectly total
(not only three variants where each piece gets pinned, but
in all three variants a total halfpin). Seems like YACPDB
files not only BBB, but also WBB as third-pin. In that case
I could offer my 192.666 Albrecht...

P1062175 has a quarterpin but can you say that it has more than one variant?
