Desk display model. A desk-scale display piece for naval history readers, submarine model collectors and anyone who wants a small, sturdy object on a shelf. It measures 3.9 in bow to rudder, sits in its own two-cradle stand, and lifts free of the base for handling.

Two hull halves, one peg. The 3.9 in hull splits at x=2.4 in and rejoins on a 0.079 in peg that buries 0.039 in into the stern and leaves 0.16 in proud. It slides into a 0.18 in horizontal socket with slip clearance, so the halves align at midship and glue holds the joint.
