Production Variations – Lower Front Hull

Factory No.200 UZTM

(Early 1944 – spare tracks fitted from July 1944)


Production Variations – Upper Rear Hull

Factory No.200 UZTM

Early 1944 – Lifting eye configuration evolved over time


Production Variations – Engine Deck

UZTMFactory No.200


Kits – Zvezda/Italeri

• UZTM production

• Pros– Dimensionally accurate– Inexpensive

• Cons– Multi-part lower hull– Detail is crude compared to DML/Tamiya– Missing some significant details– Mix of production features from different periods


Kits – DML/Cyber-hobby

• Factory No.200 production

• Pros– Full range of variants– Excellent standard of molding

• Cons– Dimensional issues

• Lower hull height (partially fixed in recent releases)• Road wheel diameter (minor)• Return roller position (minor)

– Mix of production features from different periods


Fixing the DML/Cyber-hobby lower hulls

All kits except Cyber-hobby #9112 (and IS-1/IS-2 #9108)

• Lower hull is 1.5mm too low

• Fix– Add 1.5mm styrene strip to front and sides– Add upper hull to lower hull– Add upper rear hull plate– Remove ~0.5mm from lower rear hull sides– Add 1.5mm to upper edge of lower rear hull plate– Test fit lower rear hull plate & adjust as necessary


Fixing the DML/Cyber-hobby lower hulls

Cyber-hobby #9112 (and IS-1/IS-2 #9108)

• Lower hull has been raised by 1.5mm– Extension to upper rear hull sides– Extension to underside of bow on upper hull molding

• But:– Extension does not cover the entire length of the hull sides– Open gap behind the top run of the tracks

• Fix– Add 1.5mm styrene strip to remainder of upper hull sides– Match to existing extension


Kits – Tamiya

• Factory No.200 production

• Pros– Dimensionally accurate– Excellent standard of molding

• Cons– Typically expensive– Lacks some minor details– Mix of production features from different periods


ISU-152

• November 1943 – 1956

• 3,242 built (1,885 until May 1945)

• 152.4mm ML-20S gun-howitzer– ST-10 telescopic sight/Hertz panoramic sight– Fluted muzzle brake

• Ammunition loading hatch in left-hand side of the lower hull

• Original return rollers lacked lightening holes– New return rollers with three lightening holes added in June 1944

• Rear hull modified in mid-1944– Rain gutter added over transmission maintenance hatch– Grab handle to supplement/replace central lifting eye

• 12.7mm DShK anti-aircraft machine gun fitted from the end of 1944– Retro-fitted to some older vehicles after repairs
