Cant tell if this is a repro or not Cobalt Mason Jars

[sunrunner]

this bottles are reproduced in India , thay use original jars to make molds.its an ok job,but cant fool a true collector.

The ground lip is a dead giveaway that these are repros. Compare this thick but very smoothly ground lip to a standard authentic ground lip Mason and you'll see a big difference.

Still good looking jars even if they are modern facsimiles. []

Even though they are fakes, may still have some good value. eBay. This one is slightly different, and apparently a scarce repro.

A scarce repro? Now I've seen everything!
