About this detail of the Tiger
The Rye Field Model "Bergepanzer Tiger 1" does not have any S-mine equipment at the rear corners, according to its instructions. The base plates in the middle and front of the tank are provided (part P1) and shown in step 14 of the instructions.
However, you should not use these metal parts on the left middle of the tank, because this vehicle had the hull of a Command Tiger. This position should have a small hole where an antenna base was formerly attached.
The real vehicle had four S-mine positions, including the protruding arms at the rear corners of the tank. When the Allies found the vehicle, the S-mine launchers were not installed but the removable arms were still attached at the back.
These rear arms are contained in the kit. They are parts F27 and F28. But Rye Field have molded the launcher base integrally with the support arms. These parts don't resemble the real situation when the launcher is removed. You should cut away the bases and keep the underlying arms, or make your own support arms.
