Okay, from the pics I looked at, they appear to be raised bulges, almost like a back-to-front venturi fairing on an aircraft (see inset zoomed in view I have added to the pic). This is U-1060 prior to launching. You may be able to determine their purpose from the attached diagram which shows the location of the stuff inside the sub, my guess is something to do with water induction or compressed air on the forward trim tank, with possibly an outlet to the rear, maybe an intake for use during a torpedo launch to keep the boat in trim after losing the weight of the torpedo, as it is right above the torpedo compensating tanks. I included the back part of the drawing simply because you may find it useful.
Still looking for a better picture.
