The 4.5 inch double diaphragm type round was the earliest pattern of the 4.5 inch rounds. The construction was very complicated and frequently gave rise to leakage problems. This round was made of cast iron, had a filling hole plug in the side of the 4.5 inch container type, and used the number 44 fuze. The burster was composed of a paper tube shellacked to the diaphragm.
