I have a LEE 1/400 "Admiral Scheer" with the early bridge - at least that´s what they claim and the reason why I bought it....in fact it is a bootleg of the Heller "Spee", the only difference is that the hull is now one-piece and suitable for motorization. They also have a dedicated Spee, this is presumably exactly the same kit. The detail is less sharp than on the Heller kits, but they managed to add nice recessed bridge windows where Heller just have raised lines. Still, it is not a "Scheer"! The one-piece hull is about 6mm narrower than the deck pieces that are supposed to fit between the sides!
The Pola is a rip-off from the 1/400 Tauro model, but isn´t this one "blown up" to 1/350 scale?
Personally, I stay away from these kits and try to get the originals even if they are more expensive. I don´t like the thought that some chinese pirate company (in fact the pirate arm of Trumpeter afaik) makes money with a blatant copy and the french company that developed the original is on the edge of bancrupcy due to dropping sales figures...
