Also there was the Hundredweight. This rolled over to the US in some instances, wrought iron Blacksmith's anvils being one which comes to mind. These were normally stamped on their sides with 3 sets of numbers, 1st hundredwt's (112lbs), next ¼ hundredwt's (28lbs) & lastly any remaining lbs. Thus an anvil stamped 1 2 3 Would weigh 112 + 56 + 3 = 171 lbs total.
