The O Scale Tucson House by Scientific Laser-Art is based on a plan in the 1917 Aladdin Homes catalog. The compact Tucson was one of Aladdin's small, two-story house designs. Homes like the Tucson are still standing, making them suitable for any post-1900 neighborhood. This laser-cut basswood kit features Tichy doors, windows and roofing. The Tucson kit is one of many Laser-Art O Scale products by Scientific.
