12 7/8" (almost 13") Vintage K Zildjian Constantinople Cymbals

This is for 2 K Zildjian Constantinople Cymbals that have Con Stamps 1+2 (somewhere between the 1900s and 1920s) They are likely concert/marching cymbals, as they are somewhat heavy and thick at about 1030 (shiny one) and 910 (darker one) grams and they didn't really have drum kit cymbals at that point in history. They are both just under 13 inches at about 12 7/8 inches. Both cymbals have vintage undersized holes but one if slightly enlarged/keyholed (no cracks there or anywhere else, though). There's some nicks on the edge of the shiny one shown in the pics but they don't seem too bad. There's some waving/denting shown in the closeups but nothing too severe and they get an "ok" seal (not too bad but certainly not perfect, as I've shown the only gaps I could find in the closeups. The cymbals have spots where they don't look perfectly round, as well, but that's very common for this era. The shiny one is missing the sig underneath the bell. There's patina and scratches and stickmarks and discoloration.
