Nutrimill is the Sister company to Bosch, and they share parts L'Equip is the distributor for both Nutri-mill and Bosch in the US.  Nutrimill has the Artiste Mixer and it has the same joints as the Bosch Mixer.  Which means the lids, the blades and the attachments all work in the Bosch.  In fact, I have A Nutrimill Artiste, and you can use either bowl in either mixer!
