I have some to sell, but sadly not the range you're looking for.
Now, basicaly, the scale is more HO intended (20mm). Most of the usual molds will make it in 25mm but the doors, windows, etc.
My biggest concern is with the quality of the mold : being used to deal with Hist Arts molds, I was expecting something better : they pretty hard and too light in the same way, so you have to 'press' them during casting in order to elude misformed shapes. With that in mind, you might be able to come with excellent texture for your sceneries.
