these are not two nuts, they are one nut with two different hexes. No locking effect. I’ll get some before and after photos of the plating work.

Scott used double nuts for a long time, especially for fastening the engine to the frame. One nut is the fastener, the second nut is a lock nut to avoid that vibration loosens the fastener. Works fine. Today’s solution would probably be a nyloc nut or Loctite 242.
On my bikes, some nuts were missing, and I made new in stainless steel from a 1″ hexagon bar. Took some time, but the result was nice.
