Looking at your photos, it your operators look like our 39-329 and 39-330. You will need new handles, however, since I'm not sure if your old ones will fit on the newer operators. Look at our 39-114L or the fold down type, 39-205. Your sash brackets look like the 39-553 and 39-554 if you need to replace them, as well.
