Crocodile Stamping Question...Circle?

I recently saw a Constance with the circle and wondered the same thing. Could even be alligator, which is a square now.
Hope someone knows. The really old bags have no mark at all.
Guess a call to Claude would solve the mystery.
The seller has two Kellys with the same markings. I'm thinking it's a variety of Alligator that is different from the Alligator typically marked with a square. If no one knows offhand, I'll ask the next time I'm in the store.
I am wondering if it could be wild alligator (or croc) as opposed to farm raised. You rarely see alligator except for wallets. I have seen two HACs in alligator.
