1935 Oil lines

[Kube]

Sorry I had forgot to add the photo.
In mid 1940, the return line was routed to the timing cover as apparently many mechanics were not installing the first routing design correctly.
The authentic lines and (especially) the fittings are super scarce. Plus, I would not trust a NOS line to hold up.
I have installed these filter systems on high point restorations. However, I have soldered up the supply line so as to avoid any failure in the old lines.
