Lovely heavy glass cruet bottle, late 1800s or very early 1900s vintage, probably Heisey or Fostoria, we think? This has a colonial panel type design and a slightly oval shape - also a pale sun purple color.
It's about 7" tall to the top of the glass stopper. The stopper is badly chipped at the bottom as shown in the photos, but the bottle looks excellent (nice and glossy, never used for vinegar, obviously!). It displays nicely with this stopper, anyway.
