Here is a toughie from way north of the border. Good blue aqua milk no name 162.4 Canada signal. Has good milkiness and dispersion of milk thru the piece and is VVNM condition, has just a small base nibble and some age patina. Book is $175 range. My price....$100 delivered. NOW $45 delivered. Had a guy ask if the dome has been popped on this piece. The darker swirl in the dome is greyish black carbon micro fizz that has formed a spinoff halo around the pinhole. This also has the sharp edged threading rather than the commonly seen square edge threads.
