My grandfather who trained in dentistry at Queen Marys Hospital Sidcup, mad we believe 110 tin faces,carefully crafted,to match the rest of the face of WW1 shell vicitms. Only 2 survive. They were the pre runner to plastic surgery and he trained under Gillies and Mc Kenzie. So unique are they that they are travelling the world but are back with me at the moment. Skulls had been destroyed along with jaw bones and he made various tools and jigs to effect the best possible result. Better than being stared at.
