These are RSR originals of a series of Porsche Parts they did in the 80’s in stainless steel. This is the RSR oil tank the factory used from 1974 onwards, but it also fits the 1973 models. They reworked it, so it fits all the RSR’s. The Porsche factory did this on purpose to fulfill the needs of all the RSR owners in the 80’s that demanded new oil tanks.

This RSR oil tank is a little bit smaller at one end to fit the 1974 G-models and the 1973 RSR’s as well.
