Rich,
I have the identical car! The color is "Sepia", and its advisable to keep it original if your looking to sell this car down the road. The color grows on you and interestingly, it was Dr. Porsche favorite color. Much said good, bad and ugly about Sepia, but its one of Porsche's unique colors.
Looks like the fuel filter was updated to the smaller cannister; however, your AC is original down to the the fabric covered red barrier hoses and compressor. Restoration could be a chunk of money, but if the engine is strong and rust not too bad, you'll have a worthy survivor well worth the investment. Before the economy started going south recently the posted value of the 73.5T was going anywhere from a low of 18K to 38K and up. You have the last of the longhood models and a strong collectible.
When probing for rust a hot spot on the early 911's is the pan under the rear seats. Rain water would weep through the worn rear window (pop-out) seal and make its way down under the rear seat cushion where it softened the metal overtime and made its way down into the pan. A notorious place for perforation.
I certainly hope you keep it original and enjoy the heck out of it. The 2.4 is one of the best engines Porsche engineered and excellent in day to day traffic. BEst of luck and congradulations on the find.
