Replacement Operators for Weather Shield Casement Windows

I have several Weather Shield Casement windows installed in 1981 that require new operators.

I have attached images of a 13.5 RH operator and the handle that was with it.

The operator has 40056 RH code and arm 45199I

I was given your website by Weather Shield as a possible source of a replace.

I will need at least (2) RH and (2) LH Operators, I may still be able to use the existing arms ?

The picture of the full arm does not reflect actual color which appears more "golden"

Thanks for you suggestion and help.
