Loks great Andrew,
The weathering is particularly impressive.
I've wanted to do a NIH Churchill myself. Where did you get the transfers?
As mentioned the tracks look great, could you talk us through the method you used please?
Couple of points for future reference though (I know you have at least one more 'churchill' on the bench.)
Gun barrels should be metal not green and if you're up to it, hollowing out the ends adds a great bit of realism.
Likewise the spades seem to be green rather than metal (any paint would wear off very quickly under use).
And a couple of the main things to remember when modelling Tamiya's Churchill....
1. The 3 panels on the side of the air vents are a post war mod and weren't present on wartime Churchills.
2. Tamiya didn't put any periscopes in the cupola, this can be done by filling the voids with plastic card, using a couple of references. (or you can steal their cromwell cupola and model an early Mk VII turret (but then you still need to add them to make the late cromwell turret with the Churchill cupola) and you'd have to remove the two bulges either side of the mantlet.)
3. Tamiya didn't include any internal detail for the commanders hatch (despite doing the loaders), this can be added easily with a good reference.
HTH,
Great work, keep it coming,
James
