It's an extremely old Pyro kit. That's about all I know about it; I remember building it when I was in elementary school. I haven't seen one for years.

It seems both ships in question were launched after WWII. So the troop transport function seems to be out of the question.
Hope this helps a little, though. Good luck.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
