I bought a Super 66 the other day(my first Oliver) and I can't find out what year it is. The tag says:160003 &amp;7196-606. Any help and I'd be greatfull! Also, how do you get it from low range to high range??? <!-- s:roll: --><img src="{SMILIES_PATH}/icon_rolleyes.gif" alt=":roll:" title="Rolling Eyes" /><!-- s:roll: -->
