As the Priest SPG was retired from Commonwealth service, some were set up as Armoured Personel Carriers and others lanquised in depots. Looking at their roomy interior once the gun was removed, some thought was given to using the chassis for a Engineer vehicle.
This vehicle ended up being the forerunner of the Current Combat Engineer Tractor used by the UK forces.

So like Claymore some digging round revealed and old (and horrible) Italeri Priest that was beginning to undergo the conversion to a Kangaroo APC. It was so horrid it got shelved.

The plan is an enclosed vehicle with a bucket and/or interchangeable dozer blade
So a session with the plastic card gets me to here

A lot of tidy up to do and final fittings such as a trip to a $2 shop to get a toy loader for a bucket
