Tecno F2 Chassis Numbers???

[MATTinSURREY]

Can someone please help in unravelling the history of an F2 Tecno please?

The car I'm told is a 1971 Tecno F2 (model TF71 I believe). The chassis number is 808 and the owner says it was raced by drivers such as Francois Cevert in 1970.

The complete history of this chassis I have from the current owner is:

I've trawlled Google and can find results that shows Cevert raced a 1970 (not 1971) Tecno in late 1970 but for the life of me can't find any chassis numbers to tie this car to the results above.

Can anyone throw light on this please as I'm considering buying the car but want to be sure it's history is accurate so I can obtain FIA papers.

Many thanks
