To my way of thinking, that price is a bit high. IF the bore ix excellent, then it might be worth it. As you probably know, the "ears" held the rear sight, so the sight on the barrel is from something else. Is he barrel original to the rifle, or is the barrel and its sight from something else?
Is the stock a modified original, or is it a nice aftermarked; from the sounds of it, it might well be a modified original, which to me is less desireable.
To be honest, there are plenty of sporterized '17's, I hold off and buy one with a very nice aftermarket stock, with modified reciever already drilled and tapped for scope mounting. I'd look for a Win. or Rem, and avoid the Eddystone.
