Yes, the iconic trademark of Sangun is the rifle with three erected rods. The original brand of Sangun was the British Birmingham Arms Company. Later, after World War I, the materials for producing weapons were used to express peace of mind. To produce bicycles, the British Lanling Bicycle Company was established. Later, in 1979, this company jointly produced Sangun bicycles with Anyang Feiying Group in Henan, China. As for you, you can't see the specific marks, and you can't tell whether it was before 1979 or after. If it was before, it would have flowed into China around the 1960s, but this possibility is very small. After all, there were very few foreign things in that era. If so, that would be surprising. . If it is a domestic product made after 1979, it should be quite valuable after so many years. It is a value-preserving thing and should be kept as an antique. . .
