Hi, I know this is an old post so I hope this info is still of some use.
This car is Tecno Formula 4 which raced in Europe, mainly Italy and UK in 1966 and 1967.
There were only 250 Tecno Formula 4s made. Three classes, one with 250c single, one with up to 650 cc twin and th third class up to 875cc 4 cylinder (Hillman Imp -Coventry Climax engine)
I purchased the Tecno Factory Works car in 2004. Took it to a show this week (August 2nd 2014) first time out in public since 1968!
I hjave created a website about these Tecno Formula 4 and if anyone has any info or would like to correct anything stated i would be very grateful for any input via the blog page.
