Sorry, late to this thread.
Something that I've started to do when sorting through my "collection"
I pull aside examples of each Recut Triangle combination.
Most have multiple plate positions so I only include one example for each combination. Some combinations I don't have so it's another thing for me to keep an eye out for.
It gets pretty interesting when you're looking for some of the more unique combinations.
It makes for a page of stamps that aren't very interesting except to some of us. But its fun.
Edit to add an example:
Below is an example of recut 12 + 17.
12 being 2 lines upper left triangle 17 being 1 line lower right triangle. That combination has 138 stamps listed so I have chosen one to mount on the page. 20R2L
