Lock for sliding glass door

A quick learner from Cambridge VT says:
Looking for this part... this is from a truth hardware double mortise lock, and the piece that connects the locking knob to the tumbler sheared off. Any ideas are welcome, thanks!

Hi there!

This resembles our 82-310 key lock. Carefully look over the dimensions and compare them to your original hardware to see if this matches what you need.
