As for when on the western front(British service) mid 1915 onwards.This is literally in service with both sides at the same time,and on most fronts.the French used it ,the Austro Hungarians had a licence to manufacture it ( the wonderful duplicity of the period

)and supplied the Germans .who in turn used it as the basis of the A7v project .
It's also useful for the interwar ,as it remained in service with the British well into the late 20's.inturn heading East when they were sold off.They also returned to agricultre and some were still working the land in the 40's,so VBCW is an option.
The only thing I'd did to the casting was to remove the thin resin in the tracks to open up the gap between the wheels,and behind the radiator,none of which is needed (I had to stop myself from getting carried away and removing it from all the wheels and front wheel)as it's designed to be left in of taken out if you choose too ,either doesn't detract from the look.
The only thing removed from the metal parts is the casting points and in the case of the figures their bases.(you don't need to but it's going in my collection so I did

)
There is an advantage to removing the bases as both figures have been sculpted to work as both driver and mate.ive included a little height in the soles of the shoes to allow for a simple knife cut to remove the bases rather than sanding .
I've also allowed an extra scale foot in height in the roof supports so you can see the engine and crew a little better.but you can remove upto 5mm off the supports to vary the height of the roof,The tall radiator variant was used rather than the square to keep the visual perspective with the slightly heightened roof.(it is a real radiator varriant believe me there are a lot ) and still work if you choose to reduce the roof height(that took some doing).in addition the choice of the narrow road wheel rather than a wider version again to tie in with the earlier feature.
The crew are in a non uniform with an oiled cloth engineers cap so you can use them with out converting them for all forces simply by painting the cap dark brown or black.(although I chose khaki ) the one shouting has a wrist watch although early not implausible ,and a leather jerkin,which can also be painted as a Donkey jacket by painting the arms the same colour.as the shoulder are subtlety marked,also the trousers are straight legged rather than putties .
The other is in a jumper and turned up sleeves he does have putties ,he also has a rag in his rear pocket and a pocket knife hanging from his belt.
It can also be built without the roof ,and there's no visible marks to suggest that there should be a roof.so no filling required.The steering column will be provided as a length of brass (not shown in the unmade picture)I used florists wire simply because I forgot the brass was for the tractor and used it to pin something else

Mark.
