looking for casement window crank operator

Question

One of the arms has the part number 30905 for a Truth window. However, the picture of the part that comes up does not match what is on there now. Pictures attached.

Thank you in advance!

That number is commonly associated with our 39-171 and 39-172. Is that the product you looked up? If so, your operator looks like an older version of these parts. The only thing I'm concerned about is whether or not your operator has an offset in the link arm, like ours. As long as it does then I think it should be okay.
