Fine picture

of the 8B Hispano-Suiza engine with one shot of the Helical Gear and Pinion but I failed to see the Pipe that seems to be in question. If it is on the engine it must be on the opposite side of the cut away. Some other pictures of WW-1 engines also! After it comes up, probably slowly, go to # 3 then to the 8B engine!
