I have, or i should say, my brother owns....I have....a mod 60, 1988 (serial beginning 12******), 40 1/2" OAL, 18 shot tube, and hold open bolt. It hasn't been shot much, and still has sticker on the fore end of stock. Is it worth that much more then the shorter, 14 shot tube model? He asked me to research it.
Sorry about crappy picture....crappy phone camera.
Oh....and it shoots good by the way! I couldnt resist putting a few tubes through it!
