Set of two 3D printed replacement hull hatch periscopes to replace the undersized kit parts and to correct the hinge and locking details which the kit has reversed in error. This version features the rubber prism cover over the head of the periscope which more commonly used on later production vehicles.  A very quick comparison with the kit parts shows that these not only correct the mistakes but offer a huge leap in terms of detail. You will need to remove a lip from inside the kit hatch and fractionally enlarge the slot to accept the new periscopes.
