Hi all, I try long time dont post any my opinions
But Im realy dont understand, why still we continue to discuss this topic ???

My English is weak to understand everything 100% and the harder it is, to express all the nuances in the dispute, this nonsense and the plumb line, tin platinum, I just do not even want to dive into all the nuances that refute it, but it's enough to understand one thing that should have stayed, a trace from soldering, a tin strip to a silver-based ring - 1
2 - it would be very well seen
3 - the inner surface of the ring, just as it gets dark - it is oxidized like the outer one (this means silver, and not tin)
4 - stupidity about the ease of engraving on the tin surface, engraving is done even on gun steel and for a very long time, which means it's a complete mess, that a plate of tin (as I read one of the assumptions, was put to facilitate engraving)
5 - the process itself, is very complicated (although as I said we do not see on any ring, traces of soldering, otherwise it would look like a sandwich)
All this theory, I am a complete failure, for what so much time to spend on it))) ???

P.S. use google traslater )))
