Item description for Mid-Late 1800s Honest Measure Whiskey Flask Strap Side Union Oval Bottle EMPTY

This is an antique, mid to late 1800s whiskey flask embossed "Honest Measure" within a circle. The Strap side Union Oval whiskey bottle is a light amethyst-lavender color (likely originally clear and tinted from long term sun or mineral exposure.). My father, an avid bottle hunter, found this flask more than 40 years ago in the ruins of an old plantation in Virginia. I would not be surprised if the bottle dated to the Civil War era as both the bottle style and location fit. The vintage, cork topped bottle (cork is missing) has many age related air bubbles in the glass and a very unevenly poured bottom. The old liquor bottle is damaged with a crack circling the bottle at center but is not rough to the touch. The bottle has not been repaired. There is some light sediment deposit from long term exposure. (See Photos) It measures about 6.5 x 3" x 1.5".
