Door knobs/escutcheons

Every original door knob in our house is ornate. Here are some of the styles we have. At some point later on, likely in the 20s they added a few extra doors and some of those have ornate locks, and some had plain ones.
The front door inside:

Front door exterior:

The two side doors on either ends of the porch have the same escutcheons and knobs as the front door, however they appear to have the knobs on the other way around (inside knob, on the outside etc)

The is the style we have on the downstairs interior doors:

The upstairs rooms all have porcelain knobs with this beautiful C20 rimlock. 

Oddly enough, the room they added on in 1923 on the back of the house has Victorian C20 rimlocks, one with an ornate iron knob not found anywhere else

One upstairs bedroom closet has this plain rimlock with a C20 keep. It is the wrong door because it won't close all the way, however I haven't yet measured to figure out which door actually belongs there.

Then there's this door to a partition between 2 rooms that has a different plain rimlock, again with a C20 keep.

Strangely enough, the other side of this same door has the escutcheon of a mortise lock!?

The knob and escutcheon for the basement door (I really hate the painted woodwork, I am in the process of stripping it all to be stained again)

2 upstairs rooms have latches in addition to the rimlocks:

An egg and dart knob escutcheon and knob found on the added on doors from the 1920s. If you pay close attention you can see the key hole was never cut out of the wood for this door!
