Yeah, that's the thing about working on older bikes. You never know exactly what combination of stupidity, abuse and repair fails lie beneath the surface. I once bought a 1975 Raleigh Sprite for $40. As I started cleaning it up, it became obvious that the owner bought it new, rode it for a couple of miles, and got a flat. It was hung upside down in the garage for forty years and sold to me as the elderly began to downsize.

as to the crank arms being trashed... half a block won't do that, but you MAY find that the previous owner went too far...
and CLEAN everything before reassembly.... then look the tapers over real close... report what you find.
get the bolts, torque them properly, and go ride again.... keep an eye on the snugness of the arms to the spindle, though... check them at every chance for a couple rides, and then every pre-ride inspection, ok?
