Need Replacement Casement Window Operator

A home owner from Franklin, WI says:
Good Afternoon,

The attached photo shows the casement window operator that are used on the casement windows in my house. I believe from doing web searches that these operators are manufactured by Truth / Dyad. Please confirm and provide a model number if possible so I can order replacements.

Thanks !

Hey, Rick. See our 39-253L and 39-253R. These appear very similar to your operator.

Dont forget to order the slider clips #39-529 since the old ones usually break when trying to remove it from the actuator arm. Is there a trick to get them to pop off without destroying them?
