Hapur, you are wrong! RPI year of foundation is 1862 and working till 1919 and then RPI was evacuated to Moscow and only in 1958 back to work. Such rings never produced after war. After war silver rings was marked with soviet hallmarks. Soviets use low quality dark and not/partially transparent enamels which makes ring looks awful, but on period was used bright and transparent high quality hot enamels.
"Famous" Latvian SS ring never was for sale. And every jeweler knows about these kiosks.
Question, you know what is KLM?
