Hi guys,
This:
http://cgi.ebay.com.au/ws/eBayISAPI....MEWA:IT&ih=022
looks exactly like so called "Conrad gearbox" (from outside), used to replace the inferior original Synta gearbox.
The only problem is, I am not sure if it has required 1:100 reduction ratio, and seller does not have a clue...
Anybody here on the forum has any experience with these?
