Not having examined them side to side I cannot say for certain, but if design is identical and dimensions are the same (including inside the skirt) then the volume would have to be the same (the same design would be desirable as they can be stamped off the same tool sets and have generally the same charicteristics as their heavier or lighter siblings) then the answer has to be in alloy composition. If the alloy is of the same spec then material has had to have been removed (likely candidates are inside the skirt)
