Help identifying a spring latch

This a finger latch from our aluminum storm windows. I need help identifying it and finding out if you offer suitable replacements. It is made of plastic but a metal one would work just as well.

Hello,

Unfortunately, your latch was discontinued and is no longer available. I'm not sure if we carry anything that would work for your repair but take a look and see if you might be able to adapt the 91-054 and 91-003M spring retainer to work for your storm sash. We can't guarantee that it would work but this would be our closest replacement option. Thanks for posting.
