I thought I did the same as you so I went online ebay and saw a Morphy Richards kneading blade that looked like the Schneider one .It was only £2.63 came today and as I was trying to fit it ,I had to lift the bowl out of the machine and hey presto there was the Schneider one that had fallen between the bowl and machine. The Morphy Richards one is the exact fit.
I now have 2. Here is the appliance code..
48260002 and it came within 3 working days
