Cees,
Well who knows, I guess anything is possible. I was trying not to mention Les Fruh's models but as you say the one in post #73 is a standard Taurus but with a straight TE wing. The one in post #77 appears to be a different model - note the number of stars on the fin - and has a shorter moment arm and a more upright rudder hinge line. I think, as a modeller from the same area, Chicago, he was following Ed's Taurus developments. But lets not get into Mr Fruh's models - Ed's are complicated enough.
This model does not has anything to do with the A version neither the B version we are talking about now.
So this is a C version then !!
Evan,
You will note that the caption to that photograph says "Doug Spreng's new model, much after the style of his earlier Orion" I wonder if that is correct as an adjacent shot shows Doug's Flat Top Stormer at the same event. As you suggest it should probably read " Ed Kazmirski's new model.................." Actually the model looks more like a modified Dunham Voltsplane to me.
