Wow so is that 5-98 the date of this shell, May 1898?

The projectile is not right for this, and we would need dimensions of casing to determine for certain it is 1.65 inch. Projectile is for a m1916 37mm infantry gun, which was used by u.s. forces in closing year of ww1 and was mass produced in interwar years.
