Help is needed replacing broken cranks

Question

I have attached photos as I am trying to find some assistance replacing these broken cranks.
The one with no handle is for a bow window with 4 small awning type windows. All are broken(sadly).
The one with the winding handle keeps falling off the track and I need 2 of those. The slider/roller keeps falling out of the track 1/2 way during opening. It's a beautiful well built home. I work hard to restore/renovate in-keeping with the character of the home.

Please let me know how you may be able to help me with replacing these cranks or crank parts.
I'm a tad bit "cranky" at the moment. (Haha).

Hey there, thanks for reaching out to us. It looks like you have an older style Andersen window. We can help, but I need you to remove each operator from their respective windows so that we can get a better look at the entire mechanism. Right now your photos show the base, but that only tells half the story. Seeing the whole part is essential for older units like this.

I feel confident that we can get you what you need. However I should mention know now, before we go any further, that any modern part I recommend will very likely require adaptation of the window sill to work. These are very old windows and right now we're looking at a potential conversion, not a direct replacement.
