Lincoln casement window controller

I have a house full of Lincoln windows that are 30 years old but still in great shape. The glass was replaced 10 years ago but now the controllers are going bad. I'm hoping you can identify them and might have a replacement for them. I will need to get 10 of each side ( 10 right and 10 left ). I think I have all the numbers I could find included in the picture. Let me know if you need any other info.

Thanks,

Jeff
