This is from a door in my mom's house. It's an Andersen of unknown vintage. One of the pictures is the only potentially identifying mark on the door itself. The latch internals seem to have frozen. I'd love advice as to what to buy for her for replacement. Thanks.

Hi there! I recommend our 82-037 deadbolt assembly and our 82-043 thumb lever. Both are Andersen brand and I am confident that these are modern versions of your older parts. Look them over and let me know if you agree.
