I suspect size differences would be due to not using fixed sized molds but rather using wooden forms with separate pieces of wood. The wood pieces would not necessarily be the same size each time. Especially since the wood pieces that would hold the slurry would wear out over time and would be replaced over time.

Older wooden forms would shrink with time. The impact is different based on the direction. If a board is cut such that the length of the board is oriented towards the vertical growth of the tree, shrinkage is less than 1%. But if the length of the board is oriented towards the width of the tree, the shrinkage may range from 2% to 12%. If the size of the block is say 4 feet, and the boards were cut across the width of the tree, those boards would over time show quite a bit of shrinkage.

Now in a modern lumber mill, boards are cut down the log, which orients towards the vertical of the tree. But suppose you are cutting a board by hand directly from a tree stump. In that case, the boards are cut across the width of the tree, and these boards would show an average of 5% to 10% shrinkage over time. In this situation, if the boards are used for several years, the wood shrinkage of the planks used for forms would result in noticeably different block sizes.
