I have found some errors about details on models of weapons and vehicules.
If it can help you for historical accuracy...
First, the model of the STG44 made by Seth Soldier have an error in the front set. The stock and the marking shows an late MP44/STG44 but have a early MP43 (1) front set. Some photos to explain what I say :
At left, the early MP43 (1) used in FH2, at right the late MP43/44/STG44. Do you see the differences on the barrel, the sight and the flash hider ?
Now it's about the Tiger 131 of the 501st SS Schwere Panzer Abteilung of the 1st Panzer SS Division 'LSSAH". Your model shows a late production tiger, but the 131 was a mid production tiger. And the pattern sheme is not exactly the same. Some photos:
I hope my post can help you, and sorry for my english !
