OKB Grigorov specializes in resin, photoetch and turned metal barrel conversions for armor. One of their latest releases is the Turret for Pz.VI Tiger H2.
This aftermarket set includes parts in grey resin, photoetch while gun barrel is made of turned metal. As you can see from the pictures, the casting of the parts is pretty good, without any bubbles in the resin, although with some small flash in some areas.
Overall, this set is well done and will require minimum cleaning of the parts for assembly. This would make for quite an interesting conversion and it is meant to be a “drop-in” replacement, without having to modify parts of the original kit.
I went ahead and assembled this turret - even if I don’t have a donor kit. The overall fit of the parts is fantastic. The only thing you need to be aware of is to properly clean the minimal “flash” around the hatch openings so the hatch covers, or the gun muzzle, would fit.
