I found the Bertram Cases.

These cases have never fired any other powder than Triple 7.

They were decapped, not sized then washed and walnut shell tumbled and put in astorage box sometime in 2005 before I went down to SA to work. This is how they came out of the box.

While looking for these to take pictures, I found a box of 45/70 that were shot with pyrodex, cleaned and put away 10-14 years ago and they are ugly.

The cases were stained but clean when put away!!!
