In order to rectify the blunder I've made some years ago and which came to light recently in BB1987's excellent AU thread 'Koko - Civil Aviation' - namely the 4-bladed propellers on Dash-8-400 (instead of correct 6-bladed), I've drawn new propeller.
Below is the blank with new props (for that model - older versions retain 4-bladed props and drawings are otherwise unaltered).
De Havilland Canada / Bombardier DHC-8 Dash-8
Also the change has been applied to other old drawings of Dash-8 than can be seen here:
