Flathead oil gallery

Thank you all for your comments.
As you know, I do not have command of the English language, only the basic one, so it is difficult for me to write what I want to comment on.
After analyzing everything they have written and seeing that my engine had installed, before I had had a modern full flow filter system including an oil radiator, elements that I removed, because it is not the original configuration I am looking for.
But I find that they have installed a grub screw as shown in the previous drawings, which I will have to remove, and in that way to have oil again under pressure in the internal horizontal conduit along the engine that lubricates the crankshaft and connecting rods.
