Hello. First post for me. Thanks in advance. My best guess is this shell came from the Brooklyn Navy Yard. Approx 4” diameter. 16” long.
Some info on 4 inch projectiles
Drawing for 4 inch Shell Cast Iron, Bureau of Ord. U.S. Navy,1889, WRA Co. from Cody Museum Digital Images (Technical Drawings).
4 inch projectile listing, US Navy 1923
US Navy Cartridge case circa 1898-
Wow! That is some specific information real quick. Thanks very much. I didn’t expect it to be from that era (that old). Do you know when the 4” guns were retired? Were they only naval guns?
I see that all the drawings are US Navy so I now assume the 4” guns were only on ships.
I don’t know enough on the subject to answer your question but you can look here:
Example of a 4 inch projectile in use during WW2:

Thanks Brian. The measurements are consistent with the Mark VI and VII - almost 16” long and almost 3” base to band. (Same as the WWII shell the shape is wrong). Anyway. Thanks for your input. I will poke around some more and see if I need to post another more specific question
