Gomann Berlin

[klaus 3338]

Friedrich Gomann got a patent on the 4. April 1926 for his conversion unit in calibre 4mm M20.
The muzzle protector was refined and used by the Police.
Of interest is the date of the patent because of the acceptance mark which we also can find on the receivers of several Lugers of this time.
Attached are the patent drawings and some photos.
