I also thought you were referring to a gearbox sprocket. I'm no solicitor, nor trader, but in my humble layman's opinion, the crank sprocket is an entirely different can of worms... For example...
Has the crank taper been ground incorrectly, altered, damaged? before you say "no" remember it is what, 50 years old, and has had how many previous owners?! Did you use a slightly incorrect key, too high, too sharp, too hard? Did you over tighten it? All these things would put stresses on the sprocket outside of its designed tolerance.
Plus, you say you aligned it with a rule and it was not bad, how bad is not bad? How bad does it have to be before it is too bad? Can you prove this?
My real point is this: if this goes to court, and the vendors insurance company uses its highly paid legal team, a team who specialise in NOTHING but trying to avoid or minimise payouts, they will have a field day opening this can of worms... at your expense.
Are you prepared to get into such a long, stressful, costly, legal battle?
Sorry Eddie, but I disagree with most of your points. There isn't much difference between the jobs the two sprockets do. Also Peter has one or two old sprockets which worked without failing fitted to the same crank. The design tolerance of a sprocket is going to cope with gross misalignment (the chain would fail first) or overtightening.
Your scenario regarding legal proceedings is exactly what dodgy traders hope goes through the mind of anyone who is considering legal action. I'm also no legal expert but Peter needs to first get an independent report regarding the sprockets merchantable quality and whether it is fit for purpose. I imagine he is going to have to spend several hundred pounds, if not thousands, to rectify damage to the bike and engine alone. The cost of a technical report on the sprocket isn't going to add much to that bill win or lose. If the sprockets found to be defective then my next step would be

Back and forth, I sway with the wind
Resolution slips away again
Right through my fingers, back into my heart
Where it's out of reach and it's in the dark
Sometimes I think I'm blind
Or I may be just paralyzed
Because the plot thickens every day
And the pieces of my puzzle keep crumblin' away
But I know, there's a picture beneath
Indecision clouds my vision
No one listens...
Because I'm somewhere in between
My love and my agony
You see, I'm somewhere in between
My
bike is falling to pieces
Somebody put
it together
Faith No More (Falling to Pieces). It was on the radio as I was typing and it seemed very appropriate. I've added a couple of words.
