Hi,
Perhaps the following actuals from museum pieces would help:
Armour for the joust (sport):
"1530 (circ.) Madrid, A, 26 - Man 79lb. 0oz
- Horse 79lb. 0oz"
War Harness:
1439 Musee d'Artillerie, Paris, G, I, Man and Horse 163lb. 0oz
1514 Tower, II, 5 - Man 64lb. 13oz.
- Horse 69lb. 3oz"
The above quote is from "The armourer and his craft" - Charles Ffoulkes
The book goes on to quote "Arms, clothes, saddlery etc." at about 30lb.
I also know that the bastard sword at the time weighed +-3lb.
Hope the above is of some help.
Cheers.
