Replacment for mortise door latch

A handy person from North Carolina says:
October 14, 2019
Sliding door from M&W. 25 years old. Spring inside of latch has broken (again). I have repaired it twice over the years by repairing and re-using the original spring but it will be difficult this time. I am looking for a replacement spring or the whole latch if i must. Can you provide me with part numbers for latch and spring?

Thanx in advance,
-Hale
