Schatton Modellbau 1:48 Set #4812
Review by Terry Ashley

Schatton Modellbau continues to expand their range of 1:48 items with the release of this resin “Kubelblitz” turret with brass 3cm MK.103 cannon which was designed to be fitted to a modified Panzer IV J chassis with a Tiger I turret ring to accommodate the larger ball turret and also had the front crew hatches offset to also allow for the larger turret ring. In the event only two “Kubelblitz” turrets were completed and they basically consisted of a ball turret mounted inside an outer coned shaped armoured mantlet shell that allowed -7° to + 80° elevation and full 360° traverse and was armed with twin belt fed 3cm MK.103 aircraft cannon slightly modified for this project.

The resin set is designed for the Bandai/Fuman Panzer IV kit but we can assume Tamiya will add a Panzer IV to their 1:48 range in the near future and the set consists of five pieces in light grey resin and two machined brass 3cm cannon barrels.

The barrels feature the unusual flattened muzzle brake with a series of seven horizontal holes fully drilled out with of course the muzzle bore also drilled out for very convincing looking barrel/muzzle brake combination.

The large ball turret is in one solid piece and includes the correct top layout of hatches and other fittings as well as the additional 30mm bolted armour plates on the front and rear of the ball and also includes the barrel adjustment screws on the barrel mounting collars. The 3cm barrels were not mounted centrally in the armoured collars but slightly offset towards the top but the small locating markers on the resin collars are offset towards the bottom, so watch this and drill two small locating holes for the barrels offset towards the top.

The upper armoured shield ring has resin film filling the centre section and this has to be carefully removed and also at the bottom of the shield are large sections of excess resin pour plugs which are quite difficult to remove due to the relatively thin shield and care and patience are needed when removing these to ensure the lower lip of the shield is not damaged, but by working slowly using a razor saw to remove the majority of the excess and then lightly sanding on a flat surface you should be able to remove this without problems.
The shield is cast quite thin and also includes the three weld joins at the sides and front as well as the raised section at the rear of the shield with of course the two cut-outs for the cannon at the front.

The lower turret ring also has the central section filled with resin film but this is easy to remove as the ring is quite sturdy and includes the two side mounting brackets for the ball turret and you will need to fit short sections of 1mm wire through the brackets into the central holes in the sides of the ball turret which should allow the turret to elevate after assembly. This ring fits into the turret ring cut-out in the top hull of the Panzer IV with the cone shield fitted in place once the ball turret is mounted but as I unfortunately don’t have a donor kit to test the fit I can’t comment on this aspect.

There is also the two lifting hooks provided in resin but you will be better using these as a guide to make the hooks from wire as the ends have to bent almost a right angles to the welded mounting pins and the resin hooks are cast flat.

The instructions are entirely in German text with line drawings showing the assembly of the parts and as this is quite straightforward there shouldn’t be any problems, one thing to watch is the drawings of the armoured shield still show the lower resin plugs attached which can cause a bit of confusion.

This is a nicely cast and detailed update set with typically finely machined metal barrels from Schatton Modellbau with the most work being in removing the excess resin plugs from the armoured shield and also finding a suitable donor kit may be a problem if you don’t already have a Bandai/Fuman kit but you can of course mount the turret on the display stand as the only surviving turret has appeared while on display at the Royal Military College at Shrivenham in the UK.

This set should appeal to anyone interested in the unusual designs to come out of Germany in the later war years and will certainly make an interesting model.

Highly recommended.
