Looking for your opinions on the fair value of a 1977-78 model 27-2 3.5" TH TT factory target stocks with no chips or cracks, some honest finish wear, original bluing approx. 85%, lock up is fine and very smooth trigger pull. No rust or non-factory modifications, screw heads appear unmolested. I know this model seems to be sought after in top end condition, but am looking for values for a shooter? Thanks for any and all comments.
