Maxi, the two on the left are either IHC or Model power. I don't remember which ones were which. They are old molds that a few companies have used. The one on the far left is still available from model power. The building on the far right is a DPM kit. I weathered the living daylights out of them! I prefer the older kits because they came with separate window frames and detail pieces. For less that $20, you get a decent starting point. The DPM kits look nice, but you better have a steady hand to paint the windows. I hope this helps. Nice progress pictures by the way.
