Help ID beach glass oblong bottom with numbers & letters

Susankoomar

Hello - I'm new to this forum and hoping someone can help me identify the origin of this clear glass oblong bottle bottom found on Campobello Island, New Brunswick, Canada (nearby towns across Passamaquoddy Bay include Lubec and Eastport, Maine). The bottle bottom has the letter "I" with a circle around it and the number 5 underneath. It also has D-126 and underneath that 55 6B and then L-9702.

The D-126 marking is the permit # for the distiller. I have traced this to the Calvert and Wolfschmidt Vodka brands. The 55 marking *may* indicate a year of manufacture - it's likely the fragment dates to the later 20th century
