The difference is their use. Nagmasho't is the baseline version with a decently protected superstructure and slightly improved protection. Basically just a Sho't remade to become an APC.
 
Nagmachon was later developed with a higher superstructure called 'doghouse' with protective armored glass and 7.62mm machine guns. Few versions were made but this one is the latest one to which all were converted:
 
Nakpadon took armor protection even further and up-armored the front with composite armor instead of the outdated Blazer ERA, got new and better side armor, lower superstructure and better protection for it as well.
 
A recon version is called Nagmapop:
 
A Combat Engineering Vehicle is called Puma:
 
And a specialized (also made in very low quantities) transport for the special engineering unit Ya'alom is called Nakpilon:
 
All these are used in very low quantities, and only where some unit must have heavy armor but doesn't yet have the Namer.

It is a Nakpadon, not a Nagmashot, but yes, your principle does apply.

May be it somethink like this?

What do you mean? I already uploaded it. 2 posts above yours. If you talked about the cupola, it's going to be difficult because they are in the background.

This has to be a Jumbo, right?

1. No.
 
2. I proposed this in my previous posts. Or RCWS similar to 30 mm AC mount on one of test tanks, but with AGS instead of 2A42.
 
Or another proposals from Slovenian company

 

 
2.5. Emm.. this is debatable IMO. Don't have time to write wall of text.
 
3. Nothing, i still have plans but not enough of will. T-72B obr 1989 is kind of lame for that thread. And i still want it to be shitposting-ish/joke thread. Although if you look at waht we are playing thread in Fiction subforum, you will see what is eating my free forum posting time. 

don't worry, it's fine.

don't bother, whatever you will find will not be a proof of video being fake. I also remember those talks, there were funny.

They praised the T-80U. And probably they were often used for exercises.

It's sparse for now, but I'll slowly but surely transfer my collection. Contribute all you got!

AFAIK it also has new firefighting system.

Israel's artillery-oriented magazine shared an interesting article by Lt Col Rafi Almagor that shares insights from the past development of the Sholef, that could be implemented in the development of the new, yet-unnamed howitzer in development.
Lt Col Rafi Almagor was one of the heads of the Sholef program.
 
The article is in Hebrew and translated to English by me:
 

 

Hi Xoon,
 
I do not have all the information you requested but this might be of interest. According to Krapke:  For the Leopard 2(A0-A4) the gun laying system or Waffennachführanlage (WNA) is known as H22.  It is a electric-hydraulic retarder control eqipped hydrostatic motor where an electric motor powers a coaxial piston pump which pumps the hydraulic fluid out of the reservoir into hydro storage cell.
 
Here is the diagram of the WNA H22:
 
 

If we are talking fin stabilized ammunition, then any meaningful differences should be a product of the specific gun, ammunition and fire control system than whether the gun is rifled or smoothbore.

I don't have any numbers, but the general rule of thumb is that when you use fin stabilized ammunition, you're going to get better accuracy from smoothbore guns than you would from rifled guns. 
So that means APFSDS, HEAT-MP, HE-MP, and practically anything that isn't HESH. And HESH loses out to HE-MP in every parameter.
 
Basically you want to use smoothbore guns.

It's head or lost head; feeder
You can read an article on this - http://btvt.info/5library/vbtt_1969_01_bashnja.htm
maybe translation will help (in russian)
 

This so called "rod" (sand rod) is used rod form a cavity in T-64  turret, then aluminum is filled into it.
 But this not a case for T-72, as the sand itself remains as filler.

This is what i have. These photos were taken at the Latrun Armored Corps Museum in Israel(not by me). The tank shown in this walk around is a prototype. It does not represent accurately the fielded units.
