daywalker I don't have any pics looking over the pilot into the cockpit of a fw190. The cockpit of this fighter was pretty cramped and I perosnally don't know of any showing what you want. Another problem is depending on the time and place during the war would have also factored in on what the pilot was wearing and equipted with. Deesrt pilots wouldn't wear a life jacket, while at the same time eastern front pilots in the winter would have had extra jacket and long heavy socks that could sometimes be seen above there boots. Also pilots has things they pick up and/or had specially made for them. The luftwaffe didn't care what you wore as long as you shot down the emeny.
What I did is gathered some pics I have of "typical" pilots Some are in 109's but the equiptment is the same on the pilot. The radio line came out of the back of the flying cap and plugged into a connector on the left side of the insterment panel right near the pilots arm on the fw190A through D and ta152. this normally was along the pilots side of tucked behind the seat some what. I think the pics give you a good idea of how the restraint belts were worn and looked. Again pilots would wear them to their perferance. This is not an area I'm highly knowledgable but may be able to help you out in.
early war pilot still unstrapped after landing, bf109E. I wonder if that hole is a payroll deduction??
