Hi ...I found 2 glass jugs today.....both in perfect condition.
Smaller one has what looks like a S665 on the bottom
Larger one has made in Canada on the bottom.
No other markings on either.....

Any info would be appreciated....thanks..........pic attached.

UPDATE......showed these to my father today...he thinks these might be old vinegar jugs....any thoughts ?????

Vinagers a good guess, could also be cider, juice, maybe even bleach though. Without a label it's a tough call, they're pretty generic.

Do I see color in the larger one? Finding colored ones or crude clear or amethyst ones can be fun. Start a set!
