Cromwell Models 1/72 Centurion AVRE
Here we can see a 1/72 resin model of the Centurion AVRE, now available from Cromwell Models in their Combat 72 range.  It's neatly moulded and easy enough to make up.  Detailing is delightful.  If you want to see an example of the real thing as a reference, then there is one on display at the Imperial War Museum site at Duxford in Cambridgeshire.  You will find some reference photos of that one which Jaymes Crowther pasted in our forum (link below).
