With my first (AFV Club) Cent (pictured above) I was determined to depict "The Very Diabolical", which served in Vietnam in 1971-72, and hence had plenty of "in theatre" mods born out of operational experience in a climate and terrain the British Centurion was not designed to operate in.
My first Cent has scratch built guards, Firestorm hull and turret bins, longe range fuel tank, stowed IR light and mantlet cover and Mousehouse resin spare wheels.
I am very happy with the result, but I also regret that I neglected to build this fine kit "Out of the Box - OOTB), which is generally what I do before embarking on more elaborate builds.
As I said, the AFV Club is a fine kit of a significant tank and - even better - a uniquely Aussie subject! Australian modellor Ossie Osbourn was the tech advisor and he obviously did his job well, because the kit is a cracker! (that's Aussie for really, really good).
However, I do have a few very minor gripes, and a more accurate description of the tank would be "Royal Australian Armoured Corps Mk 5/1 (Vietnam version) 1968-69".
Just as no battle plan survives contact with the enemy, so do few vehicles remain in their "as issued" form when being operated in conditions they were never designed for.
The Aussie Cents arrived in Vietnam in the configuration they were exercised in Australia - complete with "bazooka plate" side skirts, which were removed after the tanks' first outing (Operation Pinaroo) because they compacted mud and vegetation around the tracks and suspension.
Apart from the removal of the plates and mounting of spare wheels on the glacis plate, the Aussie Cents were essentiially a standard British Mk 5 or 6.
However, operational experience soon saw a lot of "Australianisation" in theatre and the Vietnam Cents eventually evolved into a unique variant.
What the AFV Club kit depicts is essentially a standard British tank (save for the .50 calibre ranging gun, IR light, bustle basket and .30 cal ammo box rack on the turret).
As previously stated, the AFV Club offering is superb and a great Aussie Cent can be built out of the box, but for me two aspects NEED to be replaced - the rubber tyres (which fit very loosely, seem to resist any glue made by man and could be prone to deterirorate down the track ... pardon the pun) and the mantlet needs a canvas cover (I've only seen a picture of one Aussie Cent without one).
Apart from the replacement of the guards with 5/16 sheet steel and the reinforcement of the hull bins, the Cents also quickly lost their smoke dischargers - which were either removed by the crews or inevitably the jungle). You can see on my previous build they are absent, but I'm going to fit them to this project to give the tank a different "look" and may even mount the light.
Although this will be an OOTB build, I have replaced the kit mantlet and tyres with the excellent Firestorm items (both of which have been reviewed by me on this site). I regard the fitting of these bits as non negotiable and I will also use Firestorm's turret basket stowage, which is an expedient nicety, but all the rest of the bits will come from the box. On my first Cent I used the Legends Centurion wheel set and they did the job, but took some fitting ... the Firestorm tyres make use the of kit wheels, which are finer detailed.

The turret has been engineered so several Marks of Centurion can be manfactured, and the joins do need some work, I will also be removing the moulded cables before resurfacing the turret - possibly after adding casting numbers.

The many handles on the engine deck are supplied with the kit, but in my experience they are difficult to remove from the sprue and fragile once installed. I replaced them all with fine fuze wire:

The glacis plate armour plate is well represented. but some weld beads are needed ... I used Milliput:

I'll give it a rest for today, but tomorrow I'll probably sand down the turret and texture it with some Mr Surfacer.
There are plenty of fine markings with the kit, unfortunately only one set is appropriate for the tank in the configuration it comes in, which is Callsign Thre One Bravo (31B) of C Squadron, Ist Armoured Regiment in 1968. The Osprey Vanguard Book The Centurion Tank in Battle has a fine illustration of the Troop leader Lieutenant G McCormack's tanks which shows the callsign in large characters on the engine deck, which will also give the tank a different look to the later "Very Diabolical" ... watch this space ....
