Support Bracket for Roto Window Operator

Dear Swisco,

We have older Roto windows and all handle operators are falling apart.
I belive it called "Support Bracket" for the handle operator.
Ours is from plastic that failed through the years but they are some from metal.

Could you help me identify to part and do you carry it?

Sincerely,
Ziv

Looks like a perfect match.
Thank you!
