Kolbe and Kolbe need to change to white

Hey there!

Thanks for reaching out to us. The casement lock in these photos looks like our 38-097 and 38-098. These are compatible with the 38-079 keeper (sold separately). The operator cover reminds me of the 39-107. Review the specifications for these parts and see if they match up with the old hardware.
