I think you could buy a spur gear from Stock Drive and carefully file the teeth to mate with the worm.
Years ago, I made a spur gear for a 44 Ton GE loco. Wasn't exactly precise, but it worked. This was probably 40+ years ago.
Like Chuck says its 13. I have a set of new ones I hope to match up with an actual replacement. Stock drive has a 13 tooth that might work but I haven't found a 19T there with a similar description. Before I start fabricating gears I will try and check all avenues for a ready made solution.
