what you have is a very nice germanic style hammer gun...the markings are unknown to me as well...you are in the right place though to find more about this fine gun...suggest you have the barrel walls measured in front of the chambers and 7 to 9 inches down from the muzzles. so long as you have at least 90 thousands of barrel wall in front of the chambers and 30 thousands down from the muzzles, you should be good to go with low pressure one ounce loads.. if you can import rst brand shells, they are highly recommended for guns like yours...enjoy...


keep it simple and keep it safe...
