The last pic of transitionals is interesting. There were a couple guys (years ago) that had put together some nice collections of those particular opaque types.
Could be? Or even Akro. I'd base that on the assumption most of the red glass is underneath and an extraordinary amount of the white ended up on the surface. Different lighting would help

Size can also factor into ID.
