On mine both the blade and the straight edge are contour cut. After looking at the pictures carefully I think I can safely say, it is identical to the one pictured.

This includes the splayed out corner mounts, mine is mounted onto a piece of timber.

One thing I have never noticed before, my moving blade is also in an arc, once again, identical looking as the picture.

Probably made by the same company and badged to whomever is re-selling, as one did back then and today as well.
