Without going out to have a look and by saying that I mean untarping LOL, the holes in the 1st are most likely for the ammo rack, the 2nd image they would be for the pioneering tool holders, unsure about what you mean in the rear end shot, cheers Dennis
ps when I get home from Dungog tomorrow afternoon (bloodbox is going for a tune up, I think I have it fairly close but I want it better) anyway I will take some images for you cheers,,.
