Someone just posted about picking up an early 70s 3 1/2" M27-2 with box and accessories for ~$1600. IMHO that was a pretty good deal. I paid $1300 for mine, same vintage, no box, about a year ago. Prices seem to be a few hundred higher now.



3 1/2" M27s pull a premium, and 3 T's are going to be harder to find on the short barrel.

I would expect a high condition shooter to bring anywhere from $1300-2000 depending on vintage, condition and box, etc. The earlier it is, the higher price it will bring, assuming otherwise comparable condition.
