Request for Replacement Window Operator Part

Hi,
I’m trying to identify a window operator to purchase from your store and have attached a photo for reference.
Key visible features:


Two spur gears


Pivoting lever/arm


Splined shaft


Three mounting holes in the baseplate


Stamped numbers: 30830 and L 30841


The gear stamped 30830 is broken, and I would like to get a replacement for this part. Could you please let me know which item I should purchase?
Thank you for your help — any information you can provide would be greatly appreciated.
Best regards,
 
Jenny
