I agree with Jani. But was not Austria a member of the C.I.P. either on July 14th, 1914 or @ the 1924 confab in Brussels after the delay of WWI?? Then the Brits brought their proof laws forward to mimic or similar on August 3rd, 1925. Austria followed suite on August 14th, 1929 being in force on September 1st, 1929. German forced all under their umbrella during the Second Great Conflict to their June 7th, 1939 rules. After the Germans marched back home in 1945, Austria rescinded the German Rules of 1939 and reverted back to the 1929 rules. Then on June 13th, 1951, a new set of Austrian Proof Rules were devised that were effective on July 1st.

I guess the question that begs is were the Brits a member??
