Searching for Pozzi Roto latch hardware

I'm sorry to say that I don't recognize the component you show in this photo. I also wasn't able to match that "WA015" code to anything in my records. Can you tell me what this piece does? Would it also be possible to see a photo of what it looks like installed? Finally, if there is more to the assembly, I'd like to see the whole thing together if possible.

These photos are exactly what I needed to see, thank you! Unfortunately, the bad news is that this isn't a component that we can help with. We did sell the lock assembly at one time, but it was discontinued in early 2013 by the manufacturer and no alternative was ever made to replace it (that we know of). I'm sorry to say that we don't sell a part that will work in this window or repair the lock mechanism at this time.

I am very sorry for the inconvenience. Your next step should be to contact a company near you that deals in Roto parts. You'll want to try to find someone who might still have a box of these in stock, though it's been a decade since we were last able to acquire these so it may be a long shot. I'm sorry again.
