I found this bottle on the shores of the Chesapeake in Maryland. There are no markings. How can I tell how old it is?
Thanks for posting your photos!
What you have is a not uncommon whiskey bottle form which is found as both machine-made (after about 1915 or so) and mold blown. Of the mold blown examples some may even have an applied lip. The first question however is how far up the neck does the mold seam go? You might also provide a clear close-up shot of the lip/ upper neck.
It sure looks to be in great shape with no barnacles or grunge so likely it was unearthed from the ocean floor by a recent storm.
