Here's an interesting Essex four. It was listed as a 1919 but I don't think so. The spark plugs are on the exhaust side and I don;t think the distributer is a Delco. That could be part of the modifications though. It has headers and duel exhaust, The generator appears to have been swapped out for an alternator. It has what looks like 4 oilers on on top of the rocker cover. I thought mine were little spring actuated breathers. Maybe they lube the rockers? Check out the oil can on the firewall.
