I’m thinking its about a 1961 motor. They made these in the 50s 60s and into the early 70s. This is a N series engine. It had a water pump on it at one point. I don’t know much about it. You are looking at the oil filter and housing off this engine. It looks like you undo the filter clean a rag and put it back together. The housing is in great shape. It needs a good cleaning. I see no reason it shouldn’t work just fine after a cleaning. The item “Old vintage cummins motor engine oil filter housing hs NHS-6-1F iron lung 220″ is in sale since Wednesday, October 5, 2016.
