Great photos, most artillery museums seem to display relatively few projectiles, especially given that there are hundreds of different types & natures of British types alone, so its nice to see a decent quantity on show. Its also unusual to find really detailed descriptions of what is displayed - though it is a rather obscure subject that is clearly overshadowed by the ordnance & their carriages etc. With my own interest in artillery, mostly confined to British muzzle loading ordnance, it is obviously difficult to collect original guns, mortars & the like, due to expense, space, availability & threats of divorce - so I find collecting projectiles followed by fuses, ignition tubes, models, parts etc is a definite substitute, as would quite a few others I presume.
