FWIW, mine originally came with white cable housings as well. According to the serial number, mine was Sept '74 built.
The original three-pin 51/39 Maxy crankset got replaced since the chainrings tended to bend/deflect under heavy load.
I don't think I had my bike even a month before ditching the downtube shifters for the SunTour barcons it still wears today.
Not sure if mine ever had brake hoods either, or if it did, I removed them to (temporarily) install safety levers since my previous bike ( all-steel '74 Fuji Special Tourer) had them and I was used to using them... I've never used hoods on this bike...
I hated the original pump with it's screw-on hose. I lost so much air when trying to remove the hose from the valvestem that I got the Zefal HP with a quick-release chuck.
Looking at the receipt, I remember that the original tires were cracked/dry-rotted, so I swapped them out at the shop for a pair of 27x1-1/8 Schwinn Super Record tires...
Over the past 42 years, that bike has gone through at least three replacement wheelsets, two rear derailleurs, numerous sets of brake pads, and probably a couple-dozen sets of tires! BUT, it still has the original Fujita Belt saddle, too! (Oh, and the Nitto handlebar stem bolt is still there, too
)
