Puzzle identifying haybob model for parts

[The Flying Nacho Farm]

I bought this haybob a few years back and am trying to search out replacement parts. Trouble is, it’s been painted over and I can’t find any identifying tags. As I recall it was sold to me as a Kuhn haybob but when I look at images online, their teeth return mechanisms look different to mine.

Can anyone tell from these pictures what model/make this is?

I’m looking for return springs, teeth and a couple of the mounting brackets for the teeth
