How the hell did i miss this build!! It's a Cent, i should of seen it first. All joking aside, looking good Bob. One thing though matey, the turret top didn't need filling. Thats where the top and bottom went together on the real tank. Why i know this? My dad drove Centurion too, 3rd Royal Tank Regiment 62 to 71. And i got into bother when i did the same to the one i built for him lol. And while i'm at it, you can fit the tracks both ways. As the box art shows they are for normal use (ie, the track pad facing upward seen from the front), but if you spin them around it gave better traction on rough ground (well, thats what my dad told me).
Anyways, if you need any help fixing a Cent i have a user handbook
33 Bravo i built for my Dad
Have fun, John
