Centuirion Mk3 Turret...weight?

[jdmcm]

So we are going to lift the Centurion turret to refurbish the fighting compartment. Of course the question is how heavy is this damn thing? We will remove the gun and mantlet prior to, but it is definitely outside the capacity of our forklift and everyone with a crane wants to know how much it weighs, lots of info out there and in the books on the weight of the tank, but I haven't found anything that has revealed the weight of the turret alone, any RCEME out there who might have an inkling?
