new tanks in 1/ 144 from a new company 4D

Last weekend I got a box of 16 new tanks easy to assemble. I bought them on Ebay, price was okay and now having the tanks in my hands, I can say even the quality is okay. As you can see on the pictures below, they do need much assembly and they are slidly prepainted. The only thing I do not understand, is the French AMX, all other tanks are WWII tanks but the AMX is an after war tank.
