Alex B, thanks my friend, but if you ask me it looks a bloody mess at the moment

. You yourself are also doing a fine speedy job there
Jon,you have absolutely no need for shame mate, she looks great

.

I specially like the pics of the un-primed build, that is very intuitive for our inexperienced builders

. As to your quest with the mantlet, I would use tissue with PVA (white) glue, the type you blow your nose on, to create the torn canvas. You'll 2 or 3 layers of it though.
James , I have noticed one thing with your gun barrel.
You should add the exhaust holes that are under the missing fume extractor. If I remember rightly

there was five 15mm holes on the 120mm Chieftain barrel, which where diagonal to the muzzle. I have searched the net but cannot find any pics of any barrel without the fume extractor, so you'll have to go with my info or leave it

.
Alex K, hi there you're doing fine dude, there is no need to rush,

yet.
You say you will not see the top run of track? In that case save the Friuls and use the kit tracks. They are not that bad anyway.
As to the pictures you only need to load the finished product into the gallery.

When you're ready I'll talk you through the procedure
