Hello,

We'd be happy to look into this for you but we would need to see your operator with the window open so that the arms that move the sash are fully visible. In the meantime, you are welcome to look through our selection of casement operators here. Thank you!

It's still difficult to make out the exact design of these arms, but they appear to match our 39-187 and 39-188. Look this design over and see if you agree.
