Great comments;

1)I have seen a few "snake skin" non stepped barrels on Enforcers. Was only able to examine one and it turned out to be a "Charnwood" assembled Enforcer. Others may have been replacements.
2) I've seen scopes numbered and unnumbered. Perhaps it was specific to the police force that owned the rifle. I believe either are correct.
3) Brian -Thanks for identifyinfy the hard case. Can you post a couple pictures. Definitely like to find one for my Enforcer.
4) Has anybody seen a one piece rail that was fixed to the receiver ring using the front holes? Told there was some set up this way as the force was dissatified with the Parker Hale 2 pc set up.
