Something, in my opinion, is a limited edition when the amounts made are significantly less than production for that company’s other models. I’d classify the K & C airplane as a limited edition because their production for other products is higher than the amounts made for the 109. However, if WP’s normal production for each and every one of its models is 100, I wouldn’t consider one of their models a limited edition. Alternatively, though you can say that production of a WP model is limited because only 100 are being made.
