Looking for a new Front Entry Door Knob

I found this excellent place online when the door knob fell off of our front door. See? Old house...fun stories.  Anyway, I called the company this morning because it's never "Plug and Play" with an old house and I wanted to be sure to get things as close to right on our first attempt as possible.

A very nice man named Paul answered the phone and kindly responded that if I will email him photos of the door with measurements he will do as much leg-work as he can to make sure we get one that fits our needs.

Paul, this post is for you. :)

Here are the knobs my husband and I have already agreed would work for what we want and suspect might have the proper measurements.

3507 Single Cylinder	Regency Lever x Lever Mortise Entry Set - PVD Lifetime; Rope Knob; RH Inswing; 2.75
N-D3 Single Cylinder	Fusion French Colonial Egg & Dart Plate Mortise Entry - 10 Beaded Egg Knob; PVD PVD Brass; RH Inswing; 2.75
3350 Single Cylinder	Albany Mortise Entry Set - PVD Lifetime; Oval Beaded Knob; RH Inswing; 2.75
3309 Single Cylinder	Versailles Mortise Entry Set - PVD Lifetime; Egg Knob; RH Inswing; 2.75
3543 Single Cylinder	Charleston Lever x Lever Mortise Entry Set - French Antique; Egg Knob; RH Inswing; 2.75

After measuring, I think the exterior plate should be 10" tall and 3" wide. Here is that photo--actually, here are two. I measured the inset at 2.75" on a RH inswing.

You can see that there is a deadbolt above the entry knob which is not included in my measurements. A deadbolt on the front entry knob we will order is not necessary, but included with most we selected.

Here's the close-up of the exterior. You can see the shape of the "original knob" with skeleton key-hole. The rectangular line is from more recent plates with "modern" rather than mortice locks.

Okay, next is the side of the door. The actual mortise opening is 3.75" deep, 1.75" wide, and 5" tall. Please excuse (and correct) me if these are not the proper words for these measurements. There is extra shaved off beyond the mortise opening to a height of 8" total that was covered with a metal plate for the most recent knob.

Okay, and last, but not least, here is the interior. Here the plate needs to be at least 7" tall and 2.5" wide.

So, here's to ordering a new entry knob that will look fantastic, be period-appropriate and ... oh, yeah, will work!! :)
