Greetings.
I believe our 1923 Sears and Roebuck home had Pella windows installed in the 80's. I have attached a couple of pictures of the awning type window that we are missing one of the knobs at the end of the straight arm which also serves as a lock. I may have some of my terms incorrect so please forgive me. We are looking to find the knob/lock for the arms.
