A truly pristine NIB example recently sold locally out of a gun shop for $1100. Didn't get to examine it in detail but it looked awful nice and considering the shop that sold it, I'd bet that it really was pristine.
With the off-center spring tunnel as noted and a "hint" of an assembly scratch in one of the views (doesn't show in the other) I'd think the $800-$900 would an appropriate price.
