Dual arm window operator

Wondering if you know what kind of window operator would be a good replacement part for the one I have in these photos? The brand is Roto I believe and there are some markings which I have included in the photos. The long arm seems to be shorter (~8.5") than the 11" ones that I have found on the site.

Hello! The one I have has an arm length of about 8 inches... this one has 11 3/8, do you know if this will still work?

I'm sorry for overlooking that! I see now you had posted that in your first post. I think I was too focused on the images.
I won't lie, that's a bit of an odd arm size for this kind of operator, but please give me a little more time to look into this and I'll get right back to you.

Hello! This is good timing. I just asked our purchasing manager for an update and I have been told that our 39-497 and 39-498 have been added to our inventory and are now available for purchase on our site. These have much smaller arms at 8-3/8". Look them over and see what you think.

Dimensions for 39-497
