Well I did say I didn't have much to do and I wasn't kidding! I scoured the spares box for the ammo boxes on the turret basket and fixed these in place. Lastly the side skirts had some details added and that's it. I have really enjoyed the build, mostly due to Tamiya's usual build quality but also because it's not something I would usually build.
It's now time to give it (and the Valentine) a very careful wash before primer.
