replacement slider door handle

You do have the older style Andersen brass handle set, yes. The bad news is that we can't supply it. I believe you need to use our 88-019 and 88-020 handles along with the 82-043 thumb latch. These parts come in a "stone" finish. As for the mortise latch, yours looks like the older style 82-263. However take a look at the 82-037 newer style mortise lock with the the anti slam button and keeper. To install this mortise you will need to use the newer keeper that is included with the lock.
