Air venturi rovair

Hello,
I have an Air Venturi Rovair 4500 that I am putting back together.
Trying to get the correct orientation of the HO cylinder assembly. The pics I took prior to disassembly disappeared. Have it repacked but am unsure how to click them. The drawings I have of the Air Venturi RovAir High Pressure Cylinder Head and Air Venturi RovAir High-Pressure Cylinder do not have a top down views.
If anyone has pictures they could post it would be greatly appreciated!
Thanks!
