Mine also takes the rotary blade F - but mine is not pictured above. I can't find a picture of it. It looks almost like both of the rotary pictured but its older so it may just have slight changes.
The background on it has some orange and the pull out bar is clear plastic, not orange.
But functionally, it looks very similar to both of those posted above.
Maybe they just make minor changes every few years so mine is not the new and improved model. But it works great. In fact I have two of them - one for home and one for crops.
