Each model is designed with utmost precision, reflective of the highest fidelity at the time of their unveiling. Structural elements may have been subtly augmented to enhance the robustness and durability of the printed model, executed discreetly to maintain authenticity. Given the 3' gauge foundation of these models, additional adjustments might be necessary to adapt them for narrower (n30) gauges or to navigate tighter-than-prototype curves. Should you require the model to accommodate a specific setting, we urge you to reach out to us prior to purchase, and we will be delighted to assist you to the fullest extent.
