Hey guys. I bought 2 tanks today from a guy off Gumtree for an excellent price. Both need work done on them. Even though I said I'd never buy one, one of the tanks is a Tiger. From uploading a picture of them on the World Rc Tank Community on FB, one member said the moulded barrel and mantlet are from anywhere between 2-3 years ago. Before I start buying parts, I would like to know if there are any differences on the external hull between the Tiger from a couple of years ago to the ones now.
