Thanks Bill for the premiere of your research here on our tiny forum.
I don't think that it will raise the price that I declare an interest in the Omegamania auction piece 
I noticed that the number of pieces produced:
1911=12.
1912=360.
1919=66 (21/24''') + 300 (21'''1/2)
Was that a reflection of the increased demand for the 1914-18 Great War?
I thought Omega did not supply the Huns in war time, so was that increase for supply to the other side?
