The cables are most likely a one piece soldered unit, with a nipple on the derailer end that can be adjusted during setup. The derailer didn't have an integral return spring, hence the two cables. The tension spring is external, runs from the derailer to a boss right behind the rear bottom bracket.

The rear fender is drilled for a skirt guard.
