This a CD 297 with I believe EIN [035] (F-Skirt) FRED M. LOCKE VICTOR N.Y./PAT'D MAY 22-94 NOV. 24 96 DEC. 15-98 SEPT. 28 97 {Note 'DEC. 15-98' date} (R-Skirt) No 16/OTHER PAT'S PENDING {MLOB} RB. The patent dates on the front are very weak, and there is a straw mark running through the first half of it. Based on the clear embossing on the rear skirt, and given this is not a narrow neck, EIN [035] is the only one that fits unless this is unlisted, which I doubt. The color is Light Aqua, and there is a 3/8" white rock to the left of No 16. There is also a cool one-inch enclosed bubble in the rear skirt below the rock as well as faint milky wisps visible when underlit. There is a small bruise in the wire groove above and to the right of No 16, another much smaller one on one ear, and a small peck above the M on the front skirt. The RB inner skirt edge is perfect as is the innermost skirt, which is almost unheard of on these. The middle skirt has a small open bubble and a few nibbles on the sharp inner edge. The rock is the standout, though! Asking $25 plus postage. I have a few more pics available on request.
