Nothing makes an interlocking tower stand out more than a detailed interior, and this HO Thirteen Lever Interlocking Machine LASERKit(R) from American Model Builders adds realism to any model tower. The kit includes a floor-cutting template for installing the levers in any of American Model Builders tower kits, a new floor plate with laser-scribed details, and a laser-cut paint mask along with color suggestions so individual levers can be appropriately painted per railroad practice. Once assembled, levers can be positioned to your liking. The finished Interlocking Machine measures 1-1/4 x 1/2 x 3/4" high; the lever bases extend below the floor level and add an additional 1/4". The Interlocking Machine is one of many HO Scale structure kits from American Model Builders.
