20mm Lübbe MG-204

Have anyone information and pics about this weapon. Never heard of it before, apparently a cannon for use on planes.

Thanks

Confusion of the origin of the "Lb" designation for the Rheinmetall-Borsig 204 gun continues. I said before that it was designated "Lb" by the factory after its designer, Heinrich Lübbe. However, it now appears more likely that stands for 'Lafette beweglich', indicating that it was intended for a flexible mounting. It appears that the beltless 20x105 round had already replaced the belted one by the time that the gun was officially adopted into Luftwaffe service as the MG 204.

This is from 'Flying Guns – World War 2: Development of Aircraft Guns, Ammunition and Installations 1933-45' by Emmanuel Gustin and myself:

"Rheinmetall-Borsig also made small numbers of a scaled-down 20 mm cannon, the MG 204 (initially known as the Lb 204, probably after the designer, Lübbe). The Lb 204, the final development of a series of experimental short-recoil guns including the Lb 201 and Lb 202, was based around the "Short Solothurn" 20x105B cartridge but was otherwise similar in operation to the MG C/30L. As it was intended for flexible mounting, it was fed by a 20-round double or saddle-drum, which it emptied at 500 rpm. The development history is now obscure but it appears that cartridge problems (possibly to do with the belt interfering with smooth feeding from the magazine) led to a change to a rimless 20x105 round and it saw limited service as the MG 204 in this form. Fixed versions, using either a 100-round drum or belt feed (MG 204G for Gurt = belt), were developed but not used."

The correction notice posted on my site (quoted by Uninen above) came later! There's an outline drawing of the gun in the book, plus size/weight data, but I don't have that up on the web.

Thanks for posting that, but the resolution is a bit low to see clearly. Is it possible to repost at higher resolution?

From the Ammo Photo Gallery on my website: the MG 204 round is the 20x105.

Ouch! That gotta hurt. But how does the machinegun itself look?
