Well I'm confused. I don't think Ball was making flasks then so I guess you meant jar? I don't see any Mason jars unless they're Ball Mason.At any rate, the blue might be 1940 or so but that's a new lid. They all look about that time range or later. They're fine to reuse but not worth much. 1940 may seam old to a young person but it's not an antique in the collector world...yet.
