Usually I don't find identification of Scott numbers 31-35 difficult. But the previous owner had these identified as three different types (as you can see from the backs. Note the back scans are in reverse order.)
But they all look like Scott 33s to me (type III).
I need some reassurance from the gang here that I'm not crazy.
Obviously the condition varies a lot between these three, but step 1: get the id right.
