I would like to replace the operational hardware for these windows. I would like to do white trim hardware if possible and fold down cranks

Hello, Trudy. We can supply the lock and operator to you, but not the window trim unfortunately. That's a bit outside of our purview.

For the lock, see our 38-075. The operator looks like an older version of our 39-028E, though you should carefully compare yours to our photos and dimensions to confirm. We also sell the 39-027E for the opposite side.
