can anyone id this swingarm?

i have never seen anything like it before.
it is kinda fugly with them triangles/wings or whatever they are.
it was custom extended but i can't figure out what bike it might have came off.
it measures 9 inches in the front.
it is 29 overall.
it's going straight to e-bay unless someone here wants it.
it appears to be strong but just nothing i would run on any of my bikes.

another

and one more

its just a box section swingarm with some weird homemade gussets

The square tube and axle adjusters look like Harley stuff, but the plate on the swingarm end is longer than any I’ve seen. The shock mounts are also throwing me off. If I had to bet I’d guess aftermarket HD.
Do the axle adjusters look like this;

Heres a picture of a R C Engineering swing arm (Honda CB 750).
It has the same type of 3 position shock mounts and also has 3 holes/slots for the axle.
