Full resin engine and gear box ( item number 352330 ) for use with the Cromwell, Comet and Centurion. The two trolleys are also included for out of the tank use but as far as I know there are none of the internal fittings needed to display these in place in the tank.
Nice little merlin kit
Yeah I have a Tamiya Cromwell that could use one. Though then I’d need to throw a lot of other stuff at it too and unfortunately although it’s cheaper that the Accurate Armour version the AA one has a lot more with it and is more suited to being mounted in the tank. If they ever do a decent interior ( even just through the hatch stuff ) I might be persuaded.
