HobbyBoss 135th GCT 155mm AU-F1 SPH Based on T-72 Full Build

Quite an interesting model. So this is the French GCT 155mm auf1 SPH but the unique thing is that it’s not on the standard amx hull, instead it sits on top of a T-72 Hull. This variation appears to only appear at an arms fair where they were trying to sell this variation to the Indian army. Can’t find too many pictures, also there are no decal markings as it is only a display model.

You can see there are 2 sets of wheels, so I guess that the other set is for the AMX hull! Quite a nice set of pieces with some Photoetch and cables. With it being a hobby boss model I expect quite a nice build.

There isn’t loads of photo etch for the GCT 155mm but a small sheet that contains some engine grilles and door handle. As you can see the grilles fit pretty nicely.

It seems most of the model building is taking place on the turret with lots of parts. Quite a cool looking turret with the huge autoload system and tons of details.

Now time for some undercoat and onto the painting. As the vehicle hasn’t seen combat I will only do some light weathering to bring out the details. I was going to leave the ammo storage doors open but my skill level in painting the shells to a good enough standard is not at the stage I am happy with.

Attaching the fuel lines to the rear of the tank and the spare petrol barrels. I thought it was going to be a lot harder to get this part done. Slipping in a conical file to each end of the vinyl tubing stretched it enough that I could ease each end over the plastic knobs.
