can anyone tell me what brand/model this roller is?

I have no clue, parts of it appear to be home made. Are there any identifying marks anywhere? Part numbers or anything?

Probably a Sin Ying or Zin Yin or sort of that name....

the side guards appear to be home made for sure from an aluminum plate i guess the previuos owner tried some modification.
there are no marks on it that i can see ajnd i had no engine when i got it niether. hopefully someone will know something.
im gonna google that name that i got and see. thanks so far guys.
anyone else ??

I'm most likely certain it's a Sinying or sort of that name because I remember few of those in 99-00 years when I was active runing buggys and some dudes bought these buggys, but basically due the fuel tank position and thos "plastic" white brake discs that are in front of the diff.....I bet is that brand I mention.
