Here is a post that will help with a feeling of the value of your prospective gun. The link is for a very nice Paragon which should have sold for the initial askance.

You will have to be objective about the condition of the gun once you have it in hand. Condition of bores, tightness of lockup, originality of finishes, condition of wood, etc., etc. Good luck with your quest.
