visitor Barry D. from Belgium, wrote to ask whether I had a copy of an advertisement
run by World Engines that featured the OS-Graupner Wankel rotary engine. I remember
seeing those ads way back in the 1970s, so I began looking at the World Engines
ads in the January 1970 issue. Finally, in the March 1972 edition, there it was.
The entire ad and a full-size scan of just the Wankel engine are shown below.
The Wankel model engine had been in the works for a few years before that as
evidenced by the article "There's a Wankel in Your
Future," in the June 1968 American Aircraft Modeler, and "Wankel Engine
Models" in the July/August 1963 American Modeler
OS-Graupner Wankel Engine in World Engines Advertisement
OS-GRAUPNER WANKEL $87.50
OS reports that they are going to increase our quota of Wankel engines in 1972.
Also, Graupner is cooperating by letting us have some of his German quota immediately.
So, if you have a Wankel engine ordered from World Engines, you may get it sooner
than we had originally promised. Price-$87.50.
