The attached image is part of a piece. I don't have a whole piece to show but I took a photo of both sides.
Is this item 23-189? Or something else? If its something else, do you have it?
Tahnks,

It's tough to say based on your pictures. I'd have to see the whole mechanism to confirm if the 23-189 is a match.
