Here is a picture of the base. Is this what is referred to as a continuous drip base? To the left where the arrow is pointing is a 3/8 inch long, 1/16 inch wide vertical line on the INSIDE of the skirt. There is a circular impression at the top of the pinhole- nearly flat, not the button of glass I am use to seeing to indicate Pennycuick style threading. Next picture [id= 158973551]

Answer: The majority opinion is "CD 134, No Embossing, [070] {Pennycuick style} "
