Apologies...I was completely wrong about 47 tooth gears.
This english mob has them..

worm gear partno. 47T 2.5-8
stepper gear partno. 12T 2.5-8
timing belt T2.5/177
All from this article

They are not cheap .. probably AU$100-110 inc postage so those europeans
are looking better all the time.
Using these will keep the hand controller functioning normally.
cheers
