Very early threaded piece-- has that threadless shape, but a threaded pinhole (which has an excellent swirl start). Condition: 1/2" dome bruise in back (no glass missing) with some minor scraping/scratching nearby. Flat shallow flake off outside skirt on rear near mold line (not visible from front), just under 1/2". Light flaking/nibbles on base associated with sharp mold line/extra glass squeezed out. Nice big strong embossing.
