How do I correct this hairspring?

[Lc130]

Hi All

I'm a beginner.  This is a FHF 28.  As you can see, the HS isn't right.  Can you please tell me how to correct it?  The last picture is one that's for sale on ebay.  It's the best pic I can find of the correct end curve.

 

 

It should look like this...but, how do I get it there?

Thank you

Charlie

I was in a similar bind about a year ago and I found this very helpful:
