That looks to be a Sugino Mighty Competition which has been painted black. Sugino made a bunch of Mighty versions in an attempt to copy the various Campagnolo cranksets from the early ’70s.
Should be 144 BCD, and will take a standard ISO square taper bottom bracket. The width of the spindle will have more to do with your frame and rear hub spacing than anything else.
In terms of restoration, strip the paint gently and then follow a polishing tutorial. These tended to crack at the tapers and the spider, so check for cracks after you strip the paint.
