Thanks scootacar for the comprehensive explanation, it all makes sence now. I must point out however that you have spelt the spelling mistake itself incorrectly and missed out the T. Now who's knit picking! These things do get ones goat though I agree, the one I cant stand is when people say Robin Reliant instead of Reliant Robin, its like saying how is your Cortina Ford! Another is the myth that bubblecars have no reverse gear, I could go on. Bye the way, have you seen Phil Bowlers Mk1 restoration, its a cracker!
