Has anyone any idea where I can obtain a motor drive shaft 16 tooth gear for this motor as mine has stripped some teeth. Regards Richard

Tony Green Steam Models normally have a good selection of gears available at reasonable prices when they visit shows and maybe they can help .

It probably important to know what the broken gear is mated to.  Knowing the motor shaft diameter is relatively simple.  Knowing the number of teeth wanted is simple enough, but it will need to work with the existing gear that the original was driving, with teeth sized, pitched and shaped to match.  That might need a new, matching driven gear as well, unless the original has/had a part number that would allow a direct replacement.
