Casement Replacement Hardware

A home owner from Philadelphia PA says:
I am looking for casement window crank and mechanism for replacement. The house was built in 1998, the crank arm cover is marked with Alcoa and the pivot arm is marked with the name truth.

I have attached a picture of the pivot arm for reference. I cannt seem to find this part on your site and need help.

I am looking for both left and right hand mechanisms.
A customer submitted photo of a window operator.

Dave Sr. from SWISCO responded:
I can't see much from the picture, but take a look at our 39-014 Casement Window Operator. Do you think that would work? If not, please submit a few pictures of the operator as removed from the window, that would help us get a better ID.

If you do choose the 39-014, please see our 39-114L for a choice in handle. Your hinge also looks a little rusted, so I recommend that you take a look at our 36-013-10.
