Please identify part

Thanks for reaching out to us. I'm sorry to say we don't sell a replacement for the latch shown here. It looks quite old so I'm afraid we aren't sure who might. I sincerely apologize that we can't be of help with this repair; please let us know if you have any other hardware questions.

The 91-112 is the only latch spring we sell. However, I don't know if this would be compatible with your old latch. Have a look at the specifications and see what you think.
