Do you mean it is unclear in practice, due to the variety of mechanisms by which production is funded, or that it is unclear in theory, due to some intrinsic problem with the concept "stock of money-capital"? It's not too difficult to construct a dynamic model in which the traditional static model of linear production theory is a fixed point. Assuming conservation of money and simple reproduction the stock of money-capital, and its relationship to the total money in circulation, is well-defined.
