In your photo "input line to fuel pump", the line you show is actually part of the vacuum system. The bottom half of the pump is for vacuum. The fuel pump is the upper half of the pump. It looks like yours has a heavy rubber line feeding the fuel in. That is a good candidate for a fuel filter as it will catch the crud before it goes into the little check valves of the pump, causing it to just idle rather than pump. The crud is usually minute rust particles from the tank.
The ring on the spring was added as part of a kit for air transport. It provided about a dozen rings on the frame, springs and bumpers to allow tie down on the aircraft pallets.
Re the 2 screws on the distributor, there was usually more than two and less than six. Personally, I prefer the higher end of that range, but when you are trying to diagnose an ignition problem at the side of the road, and the sharp little fording cable (among other things, including frayed ignition wires) have repeatedly poked through your skin, drawing blood, one can lower one's standards a little. You will find those screws need a couple different screwdrivers to install due to the awkward angles. And if you think working on a 53 is tough, wait until you work on the later ones with the big honking heater and tray blocking your access.
The grey paint on the engine, right over the grease and dirct accumulations, is the sign of a poor man's overhaul. We used to have another name for that kind of rebuild, but it is no longer politically correct. In fact, I doubt it ever was.
