Thanks Gaspare I'm trying to do my best. Once promised to myself to focuse only on WESTWALL and TOTENKOPF rings but Polish rings are also interesting (not only military). For instance I have this one. It is 100 ywaers anniversary ring of WTC (Warsaw Bicycle Assotiation). It was formed in 1886 and the ring is dated 1986. Here is some info about WTC (polish unfortunetly only but a lot of nice period pictures): http://www.wtc.waw.pl/
