I had found only two of these. The other are therefore these:

1 g4 d6 2 Bh3 Bf5 3 gxf5 Qd7 4 f6 Kd8 5 fxe7+ Kc8 6 e8=R#

(both C+ Popeye in under a second). Same basic idea, different pinner.

I don't see how I deserve this credit, since I likely wouldn't have even
tried to find such a position had you not given the summary of the
computer results. This is basically a case of you posting a puzzle
and me being the first (other than you) to solve it.
