Any old Charles Daly's out there? Kinda looking for 20x20x?
There probably are. Many of the old Charles Daly drillings were commissioned by that New York import firm to be made in common American chamberings. The two German firms that I know made them were Lindner and Sauer, but the could have been others.
As an example, I had a Daly-Sauer hammer gun in 12x12/.30-30, which I hunted with for a number of years. They also came in 20-gauge and 10-gauge, along with 16, but not 28 and .410. The rifle chamberings ranged from .25-20 WCF to .45-70, including 25-35 and .38-55.
