My wife has had this flask since her Great Aunt passed. Her Great Aunt lived on Prospect Park in New York about 1900 - 1920s, but travelled all over the world. My wife has inherited several interesting pieces, but I have not been able to identify this one or its marks. I can not find anything that resembles the marks with either British or American silversmiths.
I have tried image searches as well and have only found two images that match this on auction sites, but they go nowhere.
Any help in identifying this heirloom is appreciated.
Thanks!
Geoff
