There aren't any D&M catalogs available between 1895-05. There are a few "missing link" ads however. I couldn't find any actual examples of the 1895-04 mitts so the illustrations will have to do.
The available illustration of an 1895 mitt. Note the two piece face and sewn pocket. The sewing was used to keep the padding in place around the outside and form a pocket in the middle.
Below an ad from 1896. Pretty much the same as the 1895 catalog illustration.
Below a catalog illustration from a 1898 Dame, Stoddard, Kendall catalog. The main change is the one piece face.
The 1905 D&M catalog shows the mitt with a pounced crescent pad and reinforced leather double palm.
