The second box is marked "50 Rifle Cartridges. 41 Caliber Short./SOLID HEAD. CENTER FIRE./COLT'S/MANUFACTURED BY THE/Winchester Repeating Arms Co.,/NEW HAVEN, CONN., U. S. A." on top and has ".41 SHORT COLT'S D.A. CENTER FIRE/RIFLE./Winchester Make." The box is full. The double action marking suggest it was marketed for the Colt Model 1877 "Thunderer" revolvers. The D.A. version has a smaller rim and was introduced in 1890.

Fine with mild overall storage wear, fading, and lead oxidation on the ammunition.
