REWARD for locating NSU/Wankel #1880 rotary engines by Graupner

[jebarger]

We are trying to locate 2 Graupner 1880 Wankel rotary engines. They
are 37.41cc and deliver around 5 HP. These are labeled as NSU/Wankel
#1880 and were made by Graupner years ago (interesting sidenote is that
these may have been made by mistake). REWARD for any lead that will
result in our acquistion of two of these. Please send private email.

Thanks
