well - we are not 100% sure. We started with a similar sized pair of gears but could not find a belt that fit them. So we found this pair in our parts bin (we call 2 pole buildings and a barn our parts bin.) They are XL and we know the we can get belts. :) We think they started life as a drive for a line printer belt. where ever other tooth was a letter. That is blowing the dust off the memory wear house. We could be wrong.
