I think Y-Weido is being defamed in error. Weido is affiliated with Eagle Design which is a toy soldier manufacturer in China. The eagle Design Panzers are original products, not copies. Country Honor Toy Soldiers are also present on Weido's Ebay site and many of these products are original too Ballista, Skorpion, Romans etc. The companies produce their own products and contract manufacture of products for other Toy Soldier companies. Products that are from other companies are so identified on the Ebay site. TG catapults and Roman figures are identified as Thomas Gunn products. TCS Panzers and figures are identified as The Collector Showcase products.
If the product is attributed correctly to the company who designed it; I fail to see how it can be considered a knock off.
Generally Toy Soldier companies are constantly copying each others products. Company A produces a Panther G and shortly their after Company B produces a Panther G. Standard business practice IMO.
