Need ID on 3pt disc

[dallenx]

I'm hoping someone can help me identify the brand name of the disc I just picked up. It's a 3pt Cat '0' hook up. The 3pt a-frame bolts to the body of the first set of 8-discs. There's a 1/2" x 2" bar under the weight box of the front discs from the a-frame back to the rear set of 8-discs which has its own weight box. The rear set bolts to this bar. The frame for each set has three oblong holes on each side so each set of four discs can be moved around. It's all white in color. Any ideas in case I need parts? The newer Brinly's look nothing like it.
