I believe it has a pitch of
32 teeth per inch of pitch diameter. To check, add 2 to the number of teeth (13+2=15) and divide by the outside diameter, in inches. You should get a number between 29 and 35.
This gear is not compatible with metric gears, which are the gears that typically use the module system. If you are looking for a source for gears that work with this one, the first stage of the black and orange gearboxes from the kit of parts should work, as should the first stage from any of the similar gearboxes from previous years.
If you can't find these gearboxes, have already used them, or just want metal gears, AndyMark has a good assortment of 32 diametral pitch gears. Unfortunately, this might take a while. Before you order, you should verify the pressure angle, it is either 14.4 or 20 degrees, Hopefully someone on here knows.
