Here is one of the more difficult railroad flasks to acquire, this is the GV-6 mold which is attributed to the Coventry, CT glassworks, circa 1830s. This is a REAL NICE example... it is very boldly embossed, nice light bright color, and in excellent condition! The embossing on these molds is a little different from the others, note that "SUCCESS" is across from "TO THE RAILROAD". As you will see, there is minimal wear on this one... it is a real nice example of this scarce flask!
