OKB Grigorov’s M109 US SPH, kit 72002

Alright, another resin + PE monster from OKB Grigorov, and despite it’s lower Cat. No. (the AT-T was 72007) I got it in the beginning of this year to build for a review.

I must say I liked the kit from first sight. Relatively small number of parts that will make for a detailed, compact model of a vehicle that has a bunch of modifications still in use today, 50 years after its introduction.

So – onto the kit.

All the parts are packaged in zip-lock bags, all protected by bubble wrap and a sturdy white cardboard box. There are

AT-T from OKB Grigorov

The weathered and completed (as of today) model. Added:

– windshield wipers – “wiped area” masked off, the rest sprayed Vallejo satin varnish;

– idlers, drive wheels and tracks;

– fire extinguishers;

– 0,3mm winch cable with scratch-built hook;

– 0,6mm RB Models tow cables with kit eyelets;

– headlamps (blackout lights);

– windows in the doors, attempted imitating seals with acrylic gel and paint;

– weathering, and a lot of it. An experiment with a new technique went so far as to lead to completely strip-down of  the paint on the hull/cargo bed assembly.

Building OKB Grigorov’s AT-T, part II

In the first part of the build I basically completed the lower half of the vehicle and the cargo bed. Back to the crew compartment.

The AT-T’s front lights reside at the very front of the bonnet/hood on metal supports. In the kit these are PE parts, which supposedly butt-join the resin engine compartment, and on top of which the lights are glued. Images of broken-off detail in my mind lead me to soldering a piece of wire (in red) through each support like this (looking from the front):

This would make the whole thing a bit stronger.

Building OKB Grigorov’s AT-T

I started construction with the chassis tub. First thing to do is gluing the back wall. Next I cut the suspension arms out of the casting block and it turned out the holes for their pins are much too small. Off with the pins, arms are drilled through, as is the tub itself – naturally observing the locations of the original holes.

I decided to use thick copper wire passing through the whole tub to make new pins. This would ease me in terms of affixing the pins and make the whole thing stronger.

OKB Grigorov’s AT-T Soviet Heavy Artillery Tractor, kit 72007

The AT-T (Russian “Artilleriyskiy Tyagach – Tyazholiy”, Artillery Tractor – Heavy) was developed in the late 1940s using elements of the T-54 MBT (notably the running gear).

The main purpose of the vehicle was to tow heavy artillery pieces like the KS-30 130mm AA gun, the S-23 180mm gun and the B-4 203mm howitzer, so the machine got a 415HP version of the famous B-2 V-12 tank diesel. The standard 5-roadwheel chassis was used for a number of recovery and engineering vehicles. Extended versions (7 roadwheels) include the P-40 „Long Track” mobile radar, and an entire family of polar expedition vehicles.
