By "Sauer Dalys" I assume you mean drillings made by Sauer and sold under the Charles Daly name? All of these I have seen are Krupp-tubed. Many have do have "Three-ring" Krupp barrels.

I remember seeing a comparsion chart somewhere of the various steel maker's tubes with either a relative strength rating or quality rating. I may have been in an old Double Gun Journal? I do remember Witten Excelsior being rated right at the top or tied for best.
