We think to be an Old kk (Kolbe) Viewport sliding patio Door (1988).

We measured the latch assembly to be .75" W x 4.375" H x 1.19" Deep. Screw hole Centerline is 3.5". The "L" is .75" to 1.0" depending where you measure. The centerline of the mortise is 3/4" from the inside door surface.

We would like a complete new/replacement handle assembly and locking mechanism.

Thanks for posting! Take a look at our 82-020 handle set and 82-218 mortise lock. Does this hardware look good to you?

Please review the dimensional information I sent.

We measured the latch assembly to be .75" W x 4.375" H x 1.19" Deep. Screw hole Centerline is 3.5". The "L" is .75" to 1.0" depending where you measure. The centerline of the mortise is 3/4" from the inside door surface.

Will the 82-218 fit?

It looks like the difference in width is attributed to that trim plate you have on your existing mortise lock. I think you might be able to reuse that with our 82-218. What do you think?
