Probably some variation of Autumn Wings.

You appear to be correct.
There also seems to be quite a bit of variety in colors for these. Going to save the seed from these (I'm presuming orange is ripe, so it'll have to be from the orange and black one, as it should be the best candidate for viable seeds) and hope I don't get some crossbred mess next year.

Note also, that these are actually C. pepo squash which cross readily with summer squash and pumpkins in the C. pepo species.
