Need help identifying mower brand

[3BPercherons]

I just picked up a used 7' rotary mower. It's in excellent mechanical condition, the deck metal is solid, the guard chains are still installed and the blades aren't chewed up. It needs a good cleaning, followed by a session with the wire brush and then some paint, but otherwise it looks to be a great deal.

Problem is, there's no data plate so I don't know brand/model. It looks like it might be an old bush hog brand, but I might be way off on that. So, if any of you can identify it - or at least point me in the right direction - from these pictures I'd greatly appreciate it.

Still looking for ideas if any of you has one. It's a lot easier to source parts when you know what mower you have

Thanks!

Update: I've contacted tech support at both Rhino and Bush Hog; both say it's not one they ever made.

With that said, other than M-F, what manufacturers paint(ed) their implements red?
