Lefevers best work, followed by Fox
I used to think L C Smith, but not anymore.
My opinion is limited by not handling some of the other early makers. I await the opinion of others with more hands on experience
I think the only issue some of us have with putting Fox in the upper echelon of fit and finish is it seems Fox was only concerned with external fit and finish. The insides of the Fox are, for lack of better words, unrefined and sloppy. Doesnt matter what grade either...they all seem to have received the same lack of attention to the insides.
Ive had numerous Lefevers apart, grade for grade they seemed to have left the factory as finely finished inside as the outsides of the gun. Parkers are very nice, Remingtons and Colts were very nicely finished as well.
