Thanks to all so far.
I do have an Accurate Armour 5.5in gun, but no way would I use that on this build
There are just so many things wrong with this concept, in a way Queeg's mounting on the Cromwell makes more sense.
But perhaps this was only a proof on concept, you can see why it got knocked on the head. That is the only photo I have found of this particular conversion. Perhaps some influence from the Archer layout was in play.
The position of the driver position is actually quite laughable, you really would not be able to see very much in any forward direction. As far as ammo carrier, I tend to agree with all the other suggestions on the use of the Crusader Gun tractor. But that concept on not having self contained ammo witht he vehichle is flawed as well.
But we are in Whiff world.. lets see what we can do to improve the basic concept.
Time for the some rough maths perhaps to see what weight saving have been made by remove of the upper hull, versus weight of gun to see what is left for other rudimentary stuff, like ammo, crew, gear.
One thought I had was move the the gun more central (the mount is not fixed yet) and have the driver position in a more original area, but incorporated some how with the Gunlayers location.
More to follow
