Came across this little flask and am drawing a blank. Bottom has a pontil, lip looks sheared, and it stands about 5 7/8 tall. Along the bottom front it has a very faint... Almost a ghost image of the letters "G A M". So what am I looking at...while it looks old...the GAM has me scratching my head... and I am getting an odd feel for this one. IS it old? Anyone know what the GAM is for? As always... Thanks for the shared wisdom!!!!
