It's funny, I didn't know about the other Aerosan diorama. I designed mine as a request from my brother as I couldn't find any other Aerosan models around. I design my models to be simple builds as I'm primarily a wargamer and I want to be able to get multiple models on the tabletop quickly.
Haha, that is a coincidence! Especially because it's such an unusual type of vehicle. Well, it's just lucky for aerosan fans! ;o)
