O.K. I have added a few more components, in this view the mounting point for the firing mechanism has been glued to the tube and the basic shape of the breech lever is seen from the side. 
This top view shows the breech opening lever and the re cocking cam pinned in place. 
Some overall views. 
The rough components get streamlined and finished off once the final shape has been established.
This sub assembly is coming along fairly well I think. 
Inside the tank.

Once again I wasn't satisfied with my first attempt at making the elevation hand wheel, so on the left is the better one. 
Looking at the dished side. 
Attached to the gun mount, as you can see the smaller details have already been added. 
The hand wheel, hub detail and other details can be seen.
Viewed from the side the structure is getting there bit by bit.

So here are the components that make up the hull gun. 
The final corrected gun cradle, notice the strengthening ribs on the inside
 
The corrected recoil guard.
The guard clipped in place.
 
 
 
 
 
 
 

The other cradle taking shape, once again it will be neatened up once everything is in place. 
This is the other side. 
With the breech block in place. 
The lower hydraulic cylinder, this one returns the gun to battery. 
The right hand side view, with the upper recoil cylinder in position. 
The elevation rack pinned in place.
The completed assembly so far. 
Everything fitted together. 
Top view. 
A view taken from outside the side hatch.

Since my last post I broke apart the gun cradle because the pivot side plate wasn't right. On the left was the part that was already glued in place, in the middle was the part I thought was correct and on the right is the final corrected part.
Here you can see the cradle in pieces. 
And hopefully this pic explains my reasoning. On the middle part I could have glued two fillets into the open areas but in the end I wouldn't have been happy with it.

A few more details have been added to the overall structure. The breech block looks rough still but will be sanded smoother when I get to it. 
A side view showing the additions of the elevation quadrant and the hand grip. 
A closeup view of the elevation gear and the hand grip which was shaped from a piece of aluminium extrusion. 
The inner view of the recoil guard, a bracket and tube have been glued in place on the left hand side of the actual mounting although they are not very evident.

I took these three pics showing the gun so far inside the tank. 
You can see the steering wheel as well as the two emergency steering levers. 
The inside will be festooned with nuts and bolts as well as the ammo containers.

Today I sanded and blended the ribs to achieve a smoother appearance. 
I added the reinforcing studs inside the attachment points, I still have to add the bolt heads. 
The guard clipped in place. 
And from a slightly different angle.

Here the breech guard is almost done, this is actually the second attempt at making this part. 
I remade it because there were certain subtleties that I had not seen before and needed to get right. I will trim the outer edges as well as the strengthening ribs when it has all dried overnight. 
Another view, I still have to add the detail inside the two mounting points.

Here you can see the progress of the recoil guard with some of the strengthening ribs being glued in place, they will be sanded down and correctly shaped when the glue has dried. 
Here it is clipped to the gun mount. 
From this view the two attachment points can be seen. 
With all the components dry fitted the assembly is starting to take shape. 
Looking from above, usually I start with the largest assemblies to define the shape then the finer details get added afterwards.
