All, I posted in the general chat thread a couple of weeks ago about some bottles I came into and (understandably given the request for help) didn't get a reply. I have pulled one bottle I am interested in knowing some more about. A couple of not great photos are attached. It is a John Root's Bitters bottle, I have read the threads about general identification, but am interested in a general appraisal, whether or not I should clean the gunk from the inside (and how), and what the best venue to sell is for a non-bottle person. Thanks in advance for your help. Tom
