I'd guess that it's a standard square-taper crank under all of that. You might be able to replace it with an aluminum single-speed/track crankset, but the chaincase complicates things. Not many cranks will have the room between the crankarm and the chainring to fit the chaincase.
Thank you kindly Jeff.
It appears to be a simple dustcap with a standard bolt beneath.
I guess I can go with an aluminum crank, but it will feel pretty lonely on this bike, since everything else is steel, (even the rims!) However, is there such a thing as an aluminum crank with a steel chainring?
I've gotten addicted to zero maintenance on this bike. Same chain and sprockets since 1989, and I've only cleaned and lubed the chain twice in that time (thanks to rear flat tires)!
