below is a link to a current auction on EBay for 10 mm stuff
note that there is are 14, 15, and 16 tooth cogs included.
I suspect that they did NOT make anything with more teeth than 16. (that is their current practice) And since no one else make 10mm stuff it does not seem that 18's would be available unless you contract out to your local machine shop!
