The short arm has a B stamped on top. And it looks like a third arm in underneath.
What part is this?
I've replaced other versions of these before.
Thank you?

Hello, thank you for posting!

Your operator resembles either the 39-031 and 39-032 or the 39-155 and 39-156 operators. The main difference is the short link arm measurement. Please compare the dimensions to your current operator to determine a good fit!
