Hi, I am starting a collection of US Navy Artillery Ammunition. My first purchase was a 30 pound Parrott Shell. Did the Navy also use the Chill Nose Solid Parrott Bolt? What about the Borrman and Hotchkiss shells? I have seen a Navy Version of the Schenkl. I would also like a small caliber round shot. Any info about size,weight and cannon type would be helpful.Thanks for any help! Doug.
