One of the centre pieces on the turret is the all-around vision commander cupola. For this I was able to get hold of the now very scarce 1/6 M4 Sherman cupola from Hoshi workshop. This is an absolute piece of art.
The main reason why I wanted this instead of the stock supplied cupola is that apart from the amazing amount of detail it’s about the only one that has real clear visor ports all round.

Commanders Periscope assembled, painted and slightly weathered. Will apply some further washes later in the build.
