To my knowledge there is no photographic evidence of the wooden elements of a 162. However there is many evidence when you go through construction manuals, take your intell from text, talk to museums und put quite a lot research in it. These taskes have been executed by my friend Vassilis Dimitropoulos from Athens, Greece. Vassilis came up with this wonderful artwork and I recommend using it as a guide on determining the panel layout of the wooden elemets of a He 162.
