105 probably had a case, not just bagged. Ours used a case with removable bags for charge. Then once you had the correct number of bags inside, the projectile was set into the case mouth to cut the bags loose from their connecting string. About the price, might be top end but if it's nice they're just as hard to find in good shape as anything else. I can find you a case here without effort... Agreed about top heavy, my 18pdr is sitting up on a spot in the basement at the corner so no one can get near it and it's leaning back into the corner...
