The Mt Clemens mineral water was the only one. There were three other mineral waters, all damaged.
Thanks for all the nice replies. Tom and I are going to put both bottles on the market, after I tumble them.
We still do not have a McKearin # for the flask, so until that happens, it sure can't be sold.
Some bottles do better on eBay, while others do better in a high end auction, so we need to decide how to get the best bang for our buck. It just goes against my grain making a buyer pay an auction company 12-15% or more.
These came out of a vacant lot and there are a couple of pits left there to dig. We are crossing our fingers, as we believe there should be an older pit.
I have my bottles in boxes but dug up this old picture of one of the ones we dug in what appears to be the same mold. Not green of course. I wouldn't worry too much about it not being categorized in McKearin as there are dozens of molds of these later flasks that are not covered. Be sure to post a picture of yours when it is cleaned. The color looks great
