First of all: Congrats on that exceptional find!

That would also be my uneducated guess but I will go one step further:
If this meteorite had had more time on its parent body, it would have
become one of those incredible impact melts like Cat Mountain or
other well-known impact melt breccias. Somehow the shock process
may have been interrupted or stopped and the meteorite been ejected
from its parent body before it underwent complete shock darkening:
a shock melt breccia in the making ... ?
Cheers,
Bernd
