A web search turned up what appear to be either builder's photographs or at least photographs made soon after delivery of Port Huron & Northwestern mogul #10 and standard type #12 on a University of Michigan-related image bank linked below. Both links confirmed for function as of this posting. No specifications are available beyond cylinder size, but both the american standard type and the mogul appear to be of conventional size and layout for their respective types and era with well-proportioned appearances.
