cant do photos right now but a question concerning a model 27-2 serial# n365xx. it is nickle and looks really good and the cylinder has an n and the #2 on it. no other n markings at all. the left grip frame has a matching assembly# with that on the yoke also a few inspector marks a t a 9 and a 3.the right grip has a u in a circle a w in a triangle.the serial # on the frame and the grip butt match.the hammer and trigger are case hardened the extractor star is blues.that is about it.i suppose only a letter would help with whether it was shipped nickle or not.it has a 3.5 inch barrel.john
