A square peg

Hi there! We don't sell a match for this peg or the handle, unfortunately. We might be able to help with the operator. I can't make any promises but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. 

Thank you! 

Our 39-380 operator comes to mind based on what I see in your photos. This uses a more standard type of handle, not the square type shown here. I apologize that we can't offer a replacement for the handle but take a look at the specifications for this operator and see what you think.
