Pretty good photos, the one of the interior looks like there are some swirls of something, maybe calcium. Can’t tell, however, swirls are a doomsday for a meteorite identification since they are indicative of formation under terrestrial conditions.
There are more test that can be performed, but they need to be accomplished in a laboratory and interpreted by an expert.
I think the verdict is the best that can be provided with the information given.
keep looking, they are out there.
