Here is truly a wonderful example of the GV-10 "LOWELL / RAILROAD" flask! Although these are attributed to Coventry, CT... Chelmsford Glass Factory or Keene, NH can't be ruled out. The embossing on this example is EXCEPTIONAL! The details are crisp, and there is little to no high point wear to be found. Another interesting characteristic is the flared out lip, certainly different than most. The color (olive amber) is light enough to see through in a window, and condition is excellent. It would be tough to find a better example!
