Dear Nathaniel, As I changed the toiletpaper roll in the second-floor back bathroom, the spindle came apart, the spring dropped to the floor, and I can't At your convenience, please look for the spring on the floor, - it is of brass, about 3/4 inch in diameter and about 3 inches long. It may have rolled under the radiator or behind the sink. If you find the spring, please place it in the sink. Meanwhile, I have inserted the spindle from the decommissioned front bathroom as a replacement, but I would like to restore the original. Thank you, Jochen
