Nothing makes an Interlocking Tower stand out more than a detailed interior, and this Thirteen Lever Interlocking Machine adds realism to any model tower. The 100% laser-cut 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" long x 1/2" wide x 3/4" high; the lever bases extend below the floor level and add an additional 1/4".
