It's the fact that they quoted the weights prior to casting to the 
pound, as if the weight was guaranteed - one would normally expect 
something like, "the bell will be approximately 3 1/2 cwts".

Assuming that they will use one of their standard gauges, why is it 
surprising that the foundry can give the c of g and moment of inertia 
prior to casting? I would have thought that it was pretty easy to 
predict these!
