I'm not a WW1 modeler, per se, but I found this website while looking for propeller information on a WW2 subject, and I thought it might be of interest to WW1 and between the wars modelers. I hope it hasn't been posted before. I was torn between this forum and the interwar forum, but think it is more appropriate here. (Julien or Mike- if you think it is more suited to the other forum, please feel free to move it!)
