Please add in the new tool to be realized for the roof camera also new cavities for the buffer plates of both locomotives and head coaches, to be used instead of the existing ones (4 left + 4 right buffers required for each base set). Please refer to the 3D drawing "new_buffers.stp" provided with these comments to create the new cavities, checking also on your side the full compatibility with the existing buffer base (and if necessary adjust the design of the fitting pin), thank you
