These are the main parts of the turret:

Building at first a rack…


…for mounting the mantlet.




The gun have to be mounted from the inside, fixing with some plastic sheets.


Accessoires at the backside of the turret:




Finishing the turret with the roof and commanders cupola.




That means, the prototype kit of the Type 97 Shinhoto Chi-Ha is ready built, but needs a lot of bolts, hinges and handholds…
