Iain that is looking really good mate, You've really captured the look of it well. Dont forget to hollow out the exhaust...you need to be able to get a 1/16th tin of compo down there......leave it for a few minutes to heat up..rev the engine and out they shoot...get the new bloke in the unit to catch them as it will be hot....First aid on his hands...then eat compo stew, Yummy.
