Here are four CD 104s. Note the extreme difference in heights. Also notice the first two have slanted skirts and the second two have tapered skirts. Then there is a CD 134.4 next to an elongated CD 134 and a second shorter CD 134. You can barely see the ring around the base of the tall CD 134. The bottom shelf has three CD 170s. The first one is a tall with a smooth base. Notice the ring at the base and even a bit of extra glass squirting out of the base mold seam. The CD 170 on the right is tall and had a Continuous Drip. It also has a ring just above the base due to too much glass dropped in y the gatherer. Pennyquick had ZERO quality control and I LOVE IT!!!!
