Hereís a crazy idea that I have no idea if it would be practical or not. What if the hull were cut just above the tracks and raised six inches or so. Would this create a usable increase in the crew compartment volume? Extra space could be used for missile gear black boxes or communications stuff and super spy gear for the recon role. Definitely not an armor guy so Iíve no idea if this would be in the world of reality or total whiffery. Iím sure this would really flip the lids on the rivet counters.

Why not do that but go for an APC with full height interior -- why should the troops have to stoop all the time.  Oh, yes ... add hand-hangers from the ceiling - like in the M-113.

That would be an interesting idea.
I was going for just a little extra room for black boxes but you could definitely pack in some scouts your way.

Just say NO to mission creep!  :icon_nif:

With the main gun removed along with the ammunition storage apparatus there would be plenty of room for the reconnaissance/surveillance related bits of kit and equipment. 

Modifying the hull to gain additional roof height in something such as the S-wagn would require some major structural work.  The extreme angle of the front glacis and the engine compartment would require a lot of reconfiguration which is fine if you are starting from scratch but to attempt something that grand on an already constructed vehicle would be a serious waste of resources and a test of one's patience from my perspective.  As the one holding this model at the moment, that kind of work is way outside of my intentions as I wanted to create an agile vehicle that would be difficult to spot at normal distances before the shooting starts.  A mission similar to the Diamler Dingo as an example but with a tracked vehicle and only slightly larger.

At least it got this thread going again! I would love to see this build finished.   ;)

The Strv 103 is a very small tank.

The third crewman is, really, squeezed in as an after-thought (he actually sits at almost 90o to the direction of travel to drive the thing & has to reach over his shoulder to access the radios) to provide an extra body to assist with maintenance tasks. His nominal roles of radio operator/reverse driver are not really required; the TC can operate the radios from his position using an existing switching system & the (front) driver can reverse the tank using cameras.

Removal of the third crewman, the gun barrel & breech, the auto-loader & the stored ammunition don't, actually, increase the available volume, or even floor space, by all that much.

You'd be hard-pressed to get a four-man squad in there without Jeff's recce equipment, even with a raised box-section roof aft of the TC & driver.

To me, Jeff's dedicated recce vehicle makes the most sense, given what can be done without a complete re-design of the hull.

Some more work done in the last couple of days on the lower rear hull and the bulldozer blade feature at the front of the hull. 

The bulldozer blade consisted of four parts plus a pair of hinge parts attached to the hull front.  The blade went together without much trouble but it had some fit issues with a couple of obvious gaps and uneven parts creating a less than smooth appearance.  Vigorous sanding addressed this issue but the gaps remain.  Close enough.  I concluded from this that the real vehicle requires that the bulldozer blade has to be manually released from the stowed position and the two separate arms have to be attached before the blade can be employed.  Definitely an interesting design.  The hinge points presented a problem in attaching securely to the hull front due to the holes being too large for the parts.  I addressed this problem by applying a healthy dose of CA glue on each part on the inside of the hull and set it aside to cure. 

With that accomplished I started looking for a suitable access door for the rear of the hull.  I found a reasonably sized door in a box of parts left over from an old Hobby craft AS-90 155mm self-propelled gun/howitzer kit that had been acquired a long time ago.  Those familiar with the AS-90 will recognize this door from the turret side wall.  The original part had small access doors for the main gun ammunition magazines at the rear of the hull which I had removed by sanding smooth.  It was also realized that my vigorous sanding efforts had created some small gaps which became more obvious as I worked on that part of the hull.  I addressed this issue by attaching some bits of Evergreen plastic strips to the inside and outside of the hull.  The outside bits may have been overkill but the gaps are gone. 

Images showing bulldozer blade extended and retracted and the access door at the rear with grab handle above the door. 

Attaching that damned grab handle was the most difficult part of this build so far.  Tamiya fast dry liquid cement is not joking around.  It was drying so quickly that the grab handle did not have time to set in place.  I finally prevailed only to have it break off while trying to take these WIP images.

Additional work on upper hull.  Attached the diesel and gas turbine exhaust parts.  One would think the larger exhaust would be the one for the gas turbine but that unit is on the left side of the vehicle and the diesel is on the right side.  The hatch located over the space that would have been where the main gun breech was positioned was also attached.  The two rectangular features at the front of the hull are now identical as I took the same part from my second S-Tank to create a matching set of containers.  The real container actually contains a pair of Swedish produced (under license) 7,62mm MAG58 GPMG, alas, no gun barrels are featured on the kit parts so they are now stowage boxes by default.  The front of the hull was also given a small modification to address the parts for the main gun that are not being used.  These were parts that are part of the flotation screen that would retain watertight integrity when erected that would allow the vehicle to swim/float in calm waters.  I added some plastic bits from the spare parts stash to make something suitable to serve the same purpose.  Not the ideal fix but it cluttered up the gaps just enough to satisfy me.

Thank you both! 

I did a bit more work last night on the lower hull.  Installed the shock absorbers and the idler wheel mounts plus the track return roller supports.  Trumpeter includes those nifty little polyethylene caps for the road wheels which might actually work if not for the permanent attachment of the idler wheel so that it does not rotate once installed.  Go figure, a static model that is really static.  No cruising around on the carpet making tank noises with this model.  Not that I would be doing that anyway.   :D

I made a calculated purchase off of eBay for the two parts runners (sprues) from the Trumpeter Strv-103C kit that will turn my Strv-103B into the "C" version.  The parts are for the fuel storage containers that are added to the open area on the sides of the hull in front of the road wheels and consist of 18 20.0-litre containers plus a framework.  The additional parts on the other sprue were identical to what was included in the Strv-103B kit which includes the flotation screen supports, the engine exhaust parts for the diesel and gas turbine and some other odds and ends that I felt were valuable enough to acquire.  Estimated delivery date is sometime next week.  At the rate I am going with this thing it will not hinder any current progress anticipated as I await delivery.

That lower hull layout - especially the way the idler-wheel mounts looks exactly like the Accurate Armour kit  :icon_vader:

Great idea getting the extra sprues.
