Roto Window Crank

A quick learner says:
The attached pictures show what we are trying to get, although it is a handle for a left handed window. The writing inside the handle indicates in the first pictures is OP06-1520 the first character is o like open. The only thing I can find online ties it to Roto windows, but I can't seem to locate the correct part. I'd like to match it if possible and we're trying to sell the house. Any help would be great!!

Good morning, and thanks for posting! Unfortunately, without seeing your operator fully removed from the window, I cannot tell exactly what operator you have. However, I do have a few suggestions for you to look at. Please see our 39-325 & 39-326 X-Drive Split Arm ROTO Operators, our 39-329 & 39-330 Inverted Split Arm ROTO Operators, and finally our 39-341 & 39-342 Casement Window Operators. Compare the dimensions and styles of these pairs to your own hardware. Do any of them match up?
A home owner from Pickering, Ontario says:
I am looking for the same crank style, but noticed that your part number which closely resembles mine (#OP06-1520) the end knob that swivels to open/close the window bends outward, ours bends inward and nests into the base. Would this be a problem if I went ahead and ordered the right hand crank? Would very much like to hear from you before I order the piece. Thanks.

Thanks for posting! That OP06-1520 actually isn't one of our numbers. Of the suggested operators above, which of the SWISCO product codes most closely resembles your own hardware?

I'm also not sure if the difference in the arm will affect how well our hardware can replace yours. I'd like to see a few pictures of your arm so that I can see exactly what it is we're dealing with. Thank you!
