6.Here is the base void of the dovetail..Look how wide the seam is on the bottom.You can also see the brush marks in the mold seam.How would they have altered the bottom with out welding capabilities is baffling to me.A hollow blow pipe type of pontil mark also suggesting the Dr. Dyott method of
of empontiling saving a second step of placing a new solid rod on the bottom before putting the bottle into the annealing oven instead using the very blowpipe which created the bottle as the holder of the bottle in the annealing oven.This tells me output was now driving this manufacturer more then when the dovetail mold was used.
The GII-72b and the GII-73 side by side.Look at how much thicker the olive green GII-72b is after the mold alteration.I believe the alteration narrowed each half of the bottle.
