This flag has been in my family for at least three generations, not sure past that. It is 13 stars, but apparently machine stitched. I suspect it is a Navy flagship flag or a centennial flag. Any information on its age, history, value, etc. will be appreciated. The family name "Lindsley" is written at the side in what appears to be blue ballpoint ink (too bad, but oh well) and there is some sort of insignia stamped on it as well, a cross and number 3. It looks like an Army insignia. Thank you very much for any help.
