I believe this to be a fixed globe lantern globe not unlike the Boston and Albany globes that turn up. Globe has a top lip diameter of just over 2 1/2" with a Bead diameter of 3", a bottom lip diameter of 3 1/2" with the bottom bead diameter of 3 15/16" and an overall height of 6 1/16. Nice heavy weight globe, durable construction.
Bottom edge has two small flea bites and possibly a 5/16 long hairline crack, see photos. Top edge looks to have only a single flea bite.
