Sliding door handle replacement

Hello! This looks like a match for our 82-087 handle set. Look it over and let me know if you had any questions.

You also mentioned you needed the internal parts. By that, I assume you meant he mortise lock? If so, I'll need to see yours before I make a recommendation. The 82-087 is compatible with about a million different mortise locks so the only way to know what you need is to see the old one.
