This Caterpillar D11R track type tractor model is mainly for display purposes. You can place it on a shelf or a model train layout to add a nice touch. When handling it, make sure to hold it gently by the body to avoid any accidental damage. Since it's a brass model, it might attract dust over time. To clean it, you can use a soft, dry cloth to gently wipe the surface. Don't use any harsh chemicals or abrasive materials as they could scratch the paint or the brass. Also, be aware of the paint wear near the front dozer blade pivot points. Try not to move the blade too much to prevent further paint loss.
