The thumb latch is broken. Don't know if I need the whole handle or just a latch. It is a putty color which seems hard to find.

Thanks for reaching out to us. We don't sell a replacement for the handle shown here, unfortunately. We sell the 82-252 and 82-253 levers but I don't know if they'll work for you. Take a look at the specifications and see what you think.
