A2B Kuo hub gears or possibly entire rear hub

Someone gave me a A2B Kuo. gears in the hub are nylon and stripped. I messaged England and got an answer that they don't have any as the model is discontinued. Guy suggested maybe south america. Anyone here have those gears, or an old hub from a Kuo (that's the folding A2B) that isn't toast?
They did not make the motor. Identify that, then try the manufacturer.

With shipping cost, you may need to replace the motor as more cost effective.
Can you post a picture,tell me the motor size,maybe i can help you.
