Worst bodge I've seen
I should have been ready for this after seeing how the seller had tried to install a 68mm cup-and-cone BB in a 70mm shell:
I suppose the BB not working saved this hub - there's nothing preventing the drive-side cone precessing inward, though the first solid push on the pedals probably would have pulled that side of the axle forward and jammed the tyre against the left chainstay...fresh grease though, nice try...

Why not? I see it, but don't know what it is or why it's preventing the cone and locknut to lock.

I have just been sorting out a bike I purchased.
very happy I have it but the previous mechanic(s) I will declare Gorillas, indifferent, neglectful or inept.
every threaded fastener had a surprise lurking.

I will confess (Father, will this count?) to using zip-ties inappropriately in the past. Way in the past. Nothing like having the exhaust system drop and drag on a freeway when you thought "oh this will hold OK for just a short drive". No, kind of obvious in hind-sight, but they are not heat-resistant.

My bodge
My Frejus TdF came with this rear axle "setup." The bike has 120mm rear spacing. No problem to use a 126mm rear hub. Just put the lock nut outside the dropout. Brilliant! (Or not.)

At least it isn't a spacer made out of the Handyman's Secret Weapon...

Several times with '70s wheels, I find a nut next to the cone and another nut/locknut on the outside of the drive-side spacers (like you show in your photo). I don't know why that's done. Just more of a pain in the ass and uses up more of my precious axle spacers when I replace it.
And of course, locknuts work by forcing each half of the pair up against one side of the thread flanks - it's a friction fit that depends on the pressure generated by elastic deformation of the interfacing bits. If you shove a great big spacer between them (often made of softer aluminium) and start putting road and pedaling loads on it it may not stay tight, which can be a Very Bad Thing.
Edit: just noted in another thread someone suggesting what happened was a shop loosening the drive side cone when removing the freewheeel. Kids today...

"I do all my own work" = "Look this thing over with fine tooth comb" when I'm buying any kind of vehicle. We've come to a point in society where most of the "mechanic" has been bred out of people.

Geez, you'd think on a vintage bike they would have had the decency to keep it period correct. #9 baling wire wrapped around the axle 4 or 5 times is the only proper kludge for C & V.
