YOUR first mistake is calling this a Silver Chrome......it isn't. SC is the matte finish seen most often on the frame of the Practical models.
This appears to be the Nickel finish and is a bit more scarce than the Silver Chrome models.
Your second mistake is saying this is at best a $700 gun. Since you don't know the difference between a Nickel HP and a Silver Chrome HP I doubt you were able to research actual values.
Part of the confusion is that the BB of guns list the Hi power Nickel/Silver chrome on the same line. It makes no comment on which one is rarer.
