Thank you all,
They are around 19mm from foot to helmet crest. They would be impossible to paint If I were to go smaller , i.e. do them specifically for 15/18mm.
Like that they are like gene enhanced built like a wardrobe slabs of muscle.
Papsikels does make some great models indeed, both for Scifi ( Aliens & Predators & Robots etc ) & Cyberpunk ( Shadowrun/Chrome Hammer style ).
