Well after getting home from work last night I quickly put one of the KV-1’s together. As the box says they do just clip together quite nicely (although I think I will glue them after cleaning them up a bit).
As you can see the model is great, it looks like a KV should and the detail is nice and crisp. Based on this I will be looking at more Zvezda models for Flames of War in the future (got my eye on the Schturmoviks for a start).
I’m still waiting for the Elefants from Battlefront.
