I am ashamed to admit that I am in the club that has broken a glass cylinder, and that was after spending a great deal of time successfully removing it from the pump with no damage. I then transported it about 50 miles with no problem. However, when removing the cylinder from a box, it dropped only about an inch onto a piece of carpet, but that shattered it. From your picture it appears your cylinder is a Hygrade from Tulsa, and that is the brand mine was.
