Weathershield casement window lock and crank installed around year 2000
Thanks for reaching out to us. Please see our 39-315 and 39-316 operators, as well as the 39-545 and 39-546 brackets if you needed them. We also sell the 39-205 handle.
For the locks, see our 38-097 and 38-098. Please note that these are not compatible with your old keeper so you will also need a new 38-079.
Finally, see our 36-048 hinge set.
All of the recommended products appear to be modern versions of your older parts and I feel confident that they will work. We unfortunately cannot supply these parts in polished chrome, though. I apologize for the inconvenience. Otherwise I do think they will all work for you. Check them out and let me know if you had any questions.
