Here is one that can definitely be confirmed to Mill Village, Stoddard NH, 1840-50s. I have dug many shards of this flask at the factory site. These GIII-12 flasks are listed as comparatively scarce, but they are fairly common. It is somewhat difficult to find one as nice as this one though! Brilliant honey-ish amber glass, strong impression, and little to no wear on the surface. Note that these molds are different than the “typical” 1/2 pint Cornucopia/ Urn flask. This “urn” is actually a basket, and the ONLY mold that looks like this. Beautiful example, in fantastic condition!
