That "Army Drab" one ( I have not seen one like it before) reminds me of some Akro corks that I have seeked for years, one of the very few Akros that will show up with some AV--the green is the thing--many marble makes with green involved will show some AV--just a recipe thing with green--hardley never intended, more than likely "recipe glass" vs purchased "Cullet glass"--just my-humble opinion here.
The "Muddy" is just killer--I just love those things.
Marble--On!!
