Found this a few years back. I guess it's time to know more about it. It is marked: LOT 14 1909 BETH. STEEL CO. W.S.P. INSP. 1 PDR COMMON STEEL SHELL MOD. OF. 1908.
Who was W.S.P.? What gun fired this? Was it used but the USN? The very top of the projectile unscrews off. The brass is a little banged up. Anything else you can add would be appreciated. Thanks.
