This is a correction set for the 1/35 Tamiya M13/40 medium tank, designed to fix the incorrect turret rotation center found in the original kit. The set replaces both the upper hull plate and the underside of the turret, allowing the turret to sit and rotate around the proper center point. While the overall appearance remains faithful to the kit parts, the upper‑hull replacement includes additional alignment and gluing guides to make assembly easier than with the original Tamiya part. These parts are intended as direct replacements and can be installed with minimal or no modification depending on the kit. All components were test‑printed to verify general fit, but small adjustments may still be necessary depending on printer differences and kit tolerances.
