Vintage Stanton cartridge — extreme lean to one side normal?

If it were me, and given the low value of that cartridge, I would trash it.  However, in your 3rd photo it looks as if the whole stylus assembly, to include the black plastic part, which inserts into the cartridge body, is twisted with respect to the brushed aluminum body.  If you were to align the black plastic with the body of the cartridge, some of the alignment error would seem to correct itself.  But still, I would not use this to play LPs that are dear to me.

Leanin'? It’s not leaning, it’s bent. It’s a bent parrot.

It's an un-cartridge, you mean.

Thanks everyone for the feedback. I am guessing this cartridge was defective from the outset and the original owner(s) probably didn't know any better. I bought it second-hand on eBay but the photos neglected to show these defects so I'm trying to return it. Worst case, I'm out ~$50.

All you have to do is to straighten it out. The ears are bent from the stress or the impact. Just unbend so it's straight. Use necessary measurements and angle tools to place it onto the perfect center and orthogonal.
