Hi there Carl!! Yes, both the SW-XAI and SW-XAII are 1/72 IHP kits. The Schneeblume is very similar to the VF-0. In the Macross time line it's an advanced fighter developed in 2040 to replace the VF-17.
Now, about the kits, I've been looking both for two years now. I don't even know if IHP made a production run of them. I had an email translated to Japanese to contact IHP and never got a response...
Here are some pics of the SW-AXI
