It is a torsion front end. I bought it second hand with it because it looked funky and it was just something to have a play with.
I uses where you put the screw on the top plate to adjust the stiffness, which makes it easy to change the setup and gets rid of the need for springs on the front end. I haven't really got to grips with it yet, but will have a play to get it how I want. But it looks good
