View of a small portion of the cylinder (Left) and a detail (Right). The detail is on the right and is a magnified view of the portion boxed in yellow in the view on the left. The cylinder is a documented as being a duplicate of cylinder 14-1700.1. It has a very rough and irregular surface texture. The grooves are barely under the surface noise. Audio may be difficult to extract. This is a more extreme example of the difference in quality between duplicates and originals.
Overview of a small portion of the cylinder (Left) and a detail (Right). The detail is a magnified view of the portion boxed in yellow in the overview. The image shows the end of the groove; the cylinder where the recording stopped. 14-1700.1 is documented as an original recording. The grooves are very clearly discerned, and the surface is very regular and smooth. This is a stark contrast to the duplicate of this cylinder.
Two cylinders one presumed to be a duplicate from a mold of the other. The cylinder with the lighter gray finish (right) is documented as being a duplicate of the darker colored cylinder (Left). Both cylinders record a Yana song, sung by Ishi.
