KO 2123 main servo drive gear

[super__dan]

Ideally looking for 3 metal main (hybrid?) drive gears for the 2123 i.e. the one that comes as plastic. I think any for an original 1000 or original 2000 series fits.

Else looking for plastic drive gears. I found out on the weekend you can buy these in packets of 3 but DMS don't have any, should be around £4.50 for the 3 if you can find anywhere that has them???
