I'm wondering if all my Marconi's were Giant Marconi after looking at your images. You OP Red Marconi look about as big as my Poblanos. I also got a couple squirrely looking peppers on my Giant Marconi plant. Seeds were from a forum member. I'm betting they were all Giant Marconi.
I planted some Red Marconi this year , seeds are from Bakers Creek so I guess I'll find out.
Also your Jimmy Nardello pepper is huge!
I do like the thick wall on the Marconi "Giant/Red"? lol.
