The "gallows" characters

[Anton]

I'd like to gather evidence of which gallows do exhibit the "gallows coverage" and which do not.

Here's what I collected so far:

Simple gallows:

p - yes
f - yes
t - yes
k - ???

Benched gallows featuring...

p - ???
f - ???
t - yes
k - ???

Can somebody please advise on the question-marked positions? Wladimir, maybe you have examples? Thx in advance.
