Danish 2cm flak

[Erik E]

Hallo!

I`m looking for the German name of the Danish Madsen 2cm flak.
Supposed to be a single barreled gun on pivot mounting (like the Mg-34 flak)

Hi Erik E

Any guns of this type that fell into German hands were taken over as the 2 cm Flugabwehrkanone Madsen (2 cm Flak Madsen for short).

Czechoslovakia, Poland, Norway, Belgium, France as well as Denmark all provided weapons of this type for German use.

The weapon itself was an air-cooled recoil-operated gun which could be mounted on a wide variety of sturdy mounts. The most common mount was a turntable rotating an a cruciform mounting but simple tripods and twin-mounts were also used. Both HE and AP rounds could be fired from ten or fifteen round magazines, but a special sixty round magazine could also be used.

Data

Length of piece: 2,250 mm
Length of barrel (L/60): 1,200 mm
Weight of gun: 52 kg
Weight complete: 307 kg
Weight in action: 260 kg
Traverse: 360 degrees
Elevation: -5 degrees to + 85 degrees
Type of feed: 10 or 15 round magazine; also special 60 magazine
Muzzle velocity (AP): 730 m/sec; (HE): 890 m/sec

The weapon was also a valid AT weapon, and placed on the At mount, it had a low silouhette. The AT version had a 30 round magazine, so I would think that the AA version had this too...

Disabled 12 German armoured vehicles at April 9th 1940...

Thanks for the info, Juha! The gun could also be mounted on a motorcycle, and on a wheelless mount

Christian,


Motorcycle mount
When did the production end? AFAIK "you" produced them during the German occupation too.

Regards, Juha

[Christian Ankerstjerne]

Yes, I believe they were produced during occupation as well. The company was disbanded after the war, though, probably as an event following the hippie-socialists that occupied Denmark after Germany left...

As for the motorcycle mount, it was possible to detach them, and in the end I wouldn't like a motorcycle fireing 20mm rounds after me.

The Madsen used its own unique ammunition, not interchangeble with that of other 20mm guns. In the pic below (from the Ammunition Photo Gallery on my website), the Madsen is the 20x120. The usual German 2cm Flak round is the 20x138B. The 20x110 is for the Hispano aircraft gun.

I'm surprised that the German "Beutename" would not include a letter indicating the Danish origin as with (t) for Czeskoslovakia, (f) for France, (e) for England, (i) for Italy, (r) for Russia, ... Or is it because it already included the manufacturer's name i.e. Madsen ?

Could it be " 2 cm Flak Madsen (d) " for instance ?

Here is our Madsen 20mm before restoration.

I'm surprised that the German "Beutename" would not include a letter indicating the Danish origin

Without being too sure, I would say it`s becouse these weapons were produced for the German, not just captured.....
You also see other examples like the 4cm Flak 28 produced at Kongsberg, Norway. This is infact a Bofors gun, but there are no (n), (s) or whatsoever.

Here is a manual in german published by the danish manufacturer:
