Old casement window operator replacement

A quick learner from Denver says:
I am looking to replace a number of casement window operators in my home, but am not sure what this type of system is called. The cranks attach directly to a bolt and move 180 degrees laterally, rather than the typical set screw/360 degree crank system. Do you know what this system is called and whether it is possible to find replacement parts?

Hi there. I am not sure we offer replacement pieces for this, but, before I give you a final answer, I'd like for my senior experts to have a look at your inquiry. Once they have completed with their review, they will reach out to you with more information. Please bear with us a little longer. Thank you.

It looks like you have a "lever" type operator which just pushes out. I don't believe it's still available, or at least I could not find it in any of my older catalogs (which date back to the early 1970's, to give you an idea of how old this part probably is). 

We have a couple window operators made for older windows but I'm not sure if they'll work for you. Take a look at the 39-020 and 39-021, as well as either the 39-504 or 39-520 track. If these will replace your originals, it would likely require significantly adapting your sill and sill trim to accept the new style. Even then there's no guarantee.

I'm sorry that we couldn't find a better replacement for you.
