you are a serious sucker for these ain't you
:D these kits are not without their little 'challenges', but they are ever so nice. And they are something different, and unique. Typically British, the chassis is 51 years old, and still in production today... why change it etc etc...

Nick, Murdo,
The fuel caps are indeed coloured to differentiate between Petrol and Diesel. Red is for petrol, and Yellow for diesel. On jerry cans the filler caps are coloured accordingly. Funny thing is that when you build a model for a (non model building) Military vehicle enthusiast, they would not know about seam lines or knock out marks, but they immediately pick up on details like the filler cap...

.
It's true that when they paint these vehicles, that the filler cap probably gets painted too, but there are plenty of pics of both coloured, and of painted filler caps. After all, after a few times being opened and closed the paint will start to rub off, a replacement capmay not have been painted etc..
It also adds a little bit of colour and definition to what can be a very monotone scheme.
Glad you like the DPM, I'm getting the hang of it now, with the next build (yep, there's another three in the pipe...

) I'll do a Blog, and I'll include a bit on how I do the DPM camo.
