Anyone know anything about these fat sacs?

So I just bought 4 fat sacs off a guy and he wasn't sure what boat they came out of or how much they weigh. They were obviously stock sacs that were pulled from a boat because they only have quick connect connections, but I have know idea which boat. I just want to know how much they weigh. Anybody have any ideas? The smaller sac dimensions are around 42x18x6? The bigger sacs look similar to my 1100 fly high sac.
