We recently purchased a cabin built in 1919 in Colorado and every time I walk a different route to get somewhere on the property I find something new. This time I have come across a tiny old glass bottle probably 4 inches tall. I guess I will describe the bottle shape as sort of cone like. The top of bottle would of had a twist on cap. On the base of bottle is a 9 or 6 with a circle around it. If someone has any helpful info about bottle I would be interested in hearing it. Thanks
