Good night: By brand and model if I enter the Google Chrome search engine, I found absolutely nothing at all. In some of those if you mention the chassis number you may get to have some luck, although in the case of a Chinese chassis I suspect the chances decrease significantly.

Well, the vertical stage is not very complicated if it has voltage, just check the vertical ic and the continuity of the yoke again
