My middle front gear is missing a tooth. How do I find the part number for this? No branding that I can see. Group set is Deore on the back and Sora road shifters. 3×9 speed.

inb4 people say it’s designed like that. Nope, that is an actual broken tooth.
Normally, I wouldn’t sweat it, there’s plenty of other teeth to take the load. But, it’s looking worn. How many miles?
Any 110 BCD middle ring with the same tooth count will work. It needs to be a middle ring with the ramps and pins for better shifting
Is there a part number stamped into the back side of the crankarm? If so, what is it?
