Heres's a projectile thats been sitting at a friends holding some bayonets for a long time. I think I weaseled it out of him but I had to try and figure it out. Seems as far as I got with identifying it was it some kind of 18 pdr? The diameter is about 83.2mm, and a length of 237mm. It flanges out to a wide open top with an outside diameter of 90mm. I really dont know but it seems too thick to me for a cannister shot of some sort.Im sure someone will know. Any help on this would be greatly appreciated. SHAKY.
