I thought I'd try out some of the N Scale buildings for my 10mm WW2 project:
The top three buildings are were purchased from the local train store, for $10-15 each. The church I bought online, I think it was $20 or so. All came pre-assembled, and will need some love to get cleaned up. In the first picture I have done just that, painting it to get rid of that plastic sheen and did some landscaping. ;-)
Stug from Arrowhead and Panzer IV from Pendraken or Arrowhead - I can't remember.
