OKB Grigorov specializes in resin, photoetch and turned metal barrel conversions for armor. One of their latest releases is the tracks for the German Tiger (P), Ferdinand and Elefant (Early)
This aftermarket set includes parts in grey resin. As you can see from the pictures, the casting of the parts is pretty good, without any bubbles in the resin and small attachment points.
This set provides 6 sections of track and the pictures show the fantastic level of detail of the tracks, both inside and outside sides. To my surprise, there were also some wheels included in the set, even when the set name only lists “Tracks” being part of it.
