This is a very, very old window operator. I don't think you'll be able to find anything like this on the market. The only solution we have that may work is our 39-020 and 39-021 operators, along with a 39-520 track. Look these over to see if you could adapt your windows to use these instead. Sorry that we couldn't find anything closer!

A handy person from CA says:
Following up to see if these worked for you. I need to replace mine too.

Thanks,

Lisa
