We do carry the 90-071 lock, which is similar to yours. The hole spacing is not the same, however, and the the 90-071 locking hook faces down, while yours faces upward. As for the silver sash lift, we have the 20-011, as well as the 20-015 which is used by Andersen windows. Look over this hardware and see what you think.
