@kla2 Well if we look at a sphere of 210mm (comp. diameter) its solid mass would be around 37.5kg. Volume = 4/3piradius[sup]3=4/3pi105[sup]3[/sup][/sup] = approximately 4.8 liter which at 7.8kg per liter equals roughly 37.5kg. But this is without the handle of course. So rounding it down to the nearest kb "size" I would say a hard style 36 would be more or less the same size. My 32 hardstyle is a bit smaller than my comp bells. I also observe that my hard style handles are significantly bigger when the bells increase in size. Not only thickness wise, but also there height/width seems to increase. This varies per brand tough so it's not the most accurate guesswork.
TLDR: anywhere between 32kg and 36kg would by my guess
@kla2 Around 36kg is where a comp bell is completely solid steel and above that weight they are filled with some lead to get up to 48kg. So around ~36kg
