If anyone is interested the Bring a Trailer thread has a US Aero America (S2) up for sale at the moment and it has some excellent photos showing cockpit, engine bay, front and rear suspension, brakes etc in wonderfully clean state.
I have downloaded most of them to allow for easier discussion and examples in the future. It might help you to download them as you can use them to discuss where the bits are if needed.
