"Although the chassis and front sheetmetal were original"
So It appears that the vehicle is made of sheet metal? looking closely at the pictures seems to confirm this, this would offer some minimal protection against schrapnel as much of it loses its punch very quickly owing to its un-aerodynamic shape. Obviously it's tissue paper when fired at by small arms.
Modeling this limited defence against schrapnel by giving it a 1 armour greatly distorts the vehicles real abilities, as in game terms it is now a fully blown APC.
So if indeed the vehicle is mild sheet metal, then the advantages (realistic) of giving it armour values of 1 are
Models some extremely limited schrapnel stopping ability of the vehicle.
disadvantages (unrealistic)?
1. Now impervious to small arms fire.
2. If you try to pick up a guns under counter battery fire in a regular sheet metal (unarmoured) truck its virtually impossible because it just get destroyed. Good and proper. However the sheet metal quad can do it very easily, this is wrong because the quad should suffer just as badly from counterbattery as any other sheet metal truck. This 'easy pickup' for the Quad also completely ignores the fact that eveyone has to get out of the quad to collect the big heavy traverse wheel, dig the gun out, collect the loose ammunition and bits and pieces, attach the limber and attach the gun.
3. The British have a very handy rear area APC, it even has a better Carrying capacity than the genuine article the M3, carrying four more troops. Its Carrying capacity only needs to be 8, rather than 16 to carry the 25 pdrs around.
4. It is unfair. There are any number of other sheet metal vehicles around that dont get armour values of 1.
