A quick look in the parts listings shows these numbers for the flywheel housings......

CJ-2A  A-439
early CJ-3A 641421
late CJ-3A  802929
early CJ-3B 802929
early M-38 801628
late M-38 804308

There are a bunch of differences between the bellhousings and there were many changes and updates made during the production of these Jeeps. Most of the part numbers will work in different applications even though they are not factory correct.

The late CJ-3A starter is not shown in the "CJ3A.info/tech/starter. Just tyhe earle and the mid arrangement (Mid 1950). Perhaps in your new book?

Is it possible that in a late, key started  CJ 3 (1953) early CJ 3B parts are used?

That page is just showing the two different CJ-3A "kick start" type starters and linkages, not the later key start type. The late CJ-3A key start is different than the early CJ-3B and the M-38 stuff.

From the web-page...
"The third starter is Autolite MCH-6203. This starter is key activated with a solenoid mounted to the top of the starter and is the closed nose type. It uses a 129-tooth flywheel. The 1965 Universal Service Manual states that the third starter was put into production with vehicle serial number 30973 and, on a different page, engine serial number 130859. By adding the prefixes 452-GB1 to the vehicle serial number and 3J to the engine number, the result is vehicle 452-GB1 30973 with engine 3J130859."

Any of the flywheels can accept the 129 tooth ring gear.

The frame stamping did not begin until 1953. I have never seen a CJ-3A frame that was stamped. I suspect the very first CJ-3Bs didn't have frame stamps either. More data is needed to determine the exact starting point of the stampings.

In 1951 the state of California used the engine serial number as the "VIN" for the title. This was very common in many states in the 'good old days'. Since then someone has replaced the original Patent Plate with a reproduction patent plate that was stamped to match the title.

- just make it mechanically sound and have some fun in the hills.

I like that approach!

Those wheels look a bit to modern to be original on a CJ-3A. Maybe original to a CJ-5.

The shape of the washer helps to compensate for the possibility of different height manifold clamping surfaces from one side to the other.

The bearings and crankshaft journals don't look too bad. Sounds like your bearings have a bit too much clearance and your oil pressure is a bit too low.

Check to be sure the master cylinder push rod is not adjusted too tight. There should be a small amount of end play when the pedal is released. Also check for a restricted brake hose to the front axle.

And the oil pickup for clogging and air leaks.

A visual check of the main and rod bearings, and then plastigauge check is a very good idea.
