here are two, my first D&M and my latest.
My first is a turn of the century mitt has some of the classic D&M features, such as the grommet web. riveted inner frame(the dark spots at the top of the mitt are rivet heads) and the oval buckle on the back. I like the two piece front section that was experimented with in the early 1900's.
My latest hasn't even been cleaned yet. It is a "Professional Model" DG912. I like the "Spider Web" and reverse button location that shows the influence of the Goldsmith buyout. All the features are patent pending so this is probably a mid 1950's model
