Don,
The DWM Swiss lugers made in 1906 started out with cross-sunburst and then switched to cross-shield (I think around 1909...)
The 1929 cross-shield is a little different that the earlier 1909 cross-shield emblem.
I am away from home, but next week will post/scan some photos to show the difference...(unless another Forum member beats me to this...hint, hint...) <img src="graemlins/xyxwave.gif" border="0" alt="[bigbye]" />
