Some unusual 1/350 scale tanks made by OKB Grigorov, a European company specializing in 1/72 armor and 1/350 submarines. They also produced a range of 1/350 armor, mostly eastern front WWII vehicles. The items are still listed on their website though they do not appear to be for sale at the moment. The packages include PE detail pieces so expect to do a little work to make these pieces look good.
