This is the 'M' version of the paddle (not the 'C' version). It has a slightly shorter shaft and a smaller flange at the top. I bought the wrong one, hence the sale of this, unopened one. NB. The item you will receive is the unopened one in the packaging. I have included a photo of another identical paddle (not included in the sale) that's not wrapped, so you can see what it looks like. It fits a lot of models - please see the table in the photos (ignore the circled model - that's my machine). The part number in the listing title is the official part number but it doesn't appear in the instructions (that I have, anyway). Any questions, please ask.
