Clean Air Package
My stock 67 dart 273 2bbl (So Cal car) has one. I believe it to be the OE part as the carb tip is metal vs the 4-5 on ebay that are plastic and it still functions (dad wasn't one to change a part unless it was shot). it has a green spring and the active coil count is the same. there is an adjusting screw on the back to reduce the tension on the spring I suspect that way it can come in at a lower manifold vacuum.

With CAP for 67 273 2bbl initial timing was 5 ATC, without CAP it was 5-10 BTC (manual - Automatic) the dist mechanical advance curve was also difference between CAP and non CAP
Oh the fun of early smog controles. Who remembers smog pumps?
