Need squash ID, maybe Flat White Boer?

I cut two squash to cook down today. I didn't think they were related at first, as one has a lot of small hatchmarks, the other had less, slightly different shapes... until I cut the second one. Definitely same type, second one might have been a hair less ripe when picked.

Both are flat, cream colored with asst scratched looking marks, pale orange flesh, really easy to remove seeds, almost no strings. The first one raw taste was reminiscent of watermelon, second one a bit more bland, but only by comparison with the first. Seeds look different, but I think that also is a ripeness thing, the first one's seeds are darker and plumper, second one has paler and flatter seeds. Both got ranked a 9+ on my 1-10 scale before they are even cooked. They'll get ranked more accurately when I taste them cooked.

Looking at Baker Creek's catalog, they list Winter Squash Seeds, Flat White Boer Pumpkin and that might be it, EXCEPT .... Either I bought them cheaply, or the neighbor bought them as decor and they sat in her yard till she was tired of them. Being as they say "We are glad to finally have seeds for this rare treasure. " and are getting 3.00 for a pack of 10 seeds, I can't imagine they were in the cheap piles both of us buy from.
EDIT: Also, they say dark orange flesh, and the reviews mention good pumpkin flavor, so far I'd call it pale flesh and a light fruity flavor.

Awesome squash, I'd love to know what they are!!  Anyone recognize them?

also the first one

second one

Seeds from first on left, second on right

Thanks for any help!  :D

They baked up still fruity-ish. I'm running with it, canning it up with some pears and cherries from the freezer and several types of juice :D

And their official ranking will be a 9.8. VERY few get ranked that high, I judge HARD.

It could be an F1 hybrid, like "Flat Stacker" from Johnny's.  Maybe "Lunar Shadow," "Moonlight," "Star 7001," or "White Knight."  It looks like the Flat White Boer is the parent of all of these, they're just tweaked a bit.

(I was curious because "stacker" pumpkins are all the rage right now, and holy cannoli, there are so many kinds.  SO many.)

Oh wow. I had no clue. I know there are fads for type, didn't realize stackers were a thing.
And none have pics of it cut, it's just decor... :P
Hey people, some of us EAT those!!!
Only one I can rule out is moonlight. They are more cream than white.
Thank you!
