I too have 1, bought it last year and needed a bit of TLC.
I have the original brochure from Dagenham Motors, and additional info i've managed to piece together. They were individually designed by the customer with various available options. The collaburation of GMD Gordon Spooner Engineering/mountune/drps disbanded within a few years, but formed after focus RS failed safety test putting production back 2 yrs and nothing to win the rallye scene. GMD said give us some motors and we'll design something, and produced the T190/230 & 230R (full rallye spec) The brochure does have a picture of the T130/140 but the mechanic that built them Baz Cannon, knows nothing of them!

let me know if you need any other info
