I visited the new Gettyburg Museum where they have an interesting display of all of the equipement of the average infantryman. It was rigged for you to pickup and see what they had to carry - the sign said the displayed equipment weighed 45 pounds. The displayed included a knapsack and bedroll.

I know the Enfield weighs almost 10 pounds, does anyone know what the weight of:
Cartridge Box
40-50 Cartridges
Cap Box
Bayonet and Scabbard
Canteen
