Regarding Cactus Jack, I've got two quick questions I hope someone can answer.

First, is there really a forend screw in the M70 Fwt. shown above, and if so, why?

Second, does anyone know what happened between he and Biesen in the later years, as referenced in "Jack O'Connor Catalogue of Letters"? Any other comments on that "book" would be interesting to hear.

Good shooting.
