I have no affiliation with this seller just passing on info.
This is an original model A wheel It very small. I own one like this that I use just for trimming.
I paid $275 for mine . I think this one may be overpriced.
I suggest you seal the flakeboard deck especially the edges and the 4 bolts that hold it down if you end up owning one.
I love my tiny wheel as it fits in a corner and is so easy to move around.
Brent re-disigned this model and its much larger now.
