In the photographs I can see some modifications that are not Topolino or even of Fiat origin.. For example The propshaft does not have the rubber flexible couplings, and the carburettor fitted looks like an AMAL and the intake manifold non- standard. The aluminium sump is a replacement for the original pressed steel part maybe of Casegrande manufacture but what is the oil pipe that emerges from the side and seems to go up into the engine compartment to some plumbing on the LHS of the engine. An explanation would be greatly appreciated. Thank you

It feeds excess oil into the sump of the engine.
