HISTORY

Widely used by many nations, the 20mm Oerlikon was arguably produced in higher numbers than any other anti-aircraft weapon of World War II. The later USA Mark 4 was the most common version built in the USA

Hellenic 5-inch/54-Caliber Mark 42 Gun Set

Hellenic Ship Model has produced a 1:72 scale 20mm Oerlikon Mark 4 which contains a total of two cannon. The print rafts come inside a clamshell plastic box. Each gun mount is comprised of the pedestal base combined with the shield and shoulder rests and a separate gun barrel incorporating the gun sight and magazine. No instructions are provided with the set, but assembly is straight-forward. Carefully remove the pedestal assembly and barrel assembly from the print raft and attach them together. The print raft also has the cartridge case collecting bag and three spare magazines. All of the parts are well detailed.

CONCLUSIONS
This accessory set from Hellenic Ship Model is very well done and easy to use. The set provides parts for two 20mm Mark 4 mounts for the price of €12.00 or about $13.90 US. This is a bargain as this breaks down to €6.00 or about $6.95 each. If you have one of the classic 1/72 scale PT Boats in your stash, this set will provide a very nice upgrade. I would like to thank Kostas Kokkinos of Hellenic Ship Model for the review sample.
