can anyone help identify this chassis ?

[my250gt]

So i have this chassis but no history. Is there any way i can identify which car it came from, whether it can have an identity or not? I Would be interested in rebuilding it and if i could relate it to an original car that would be a bonus and make it more worthwhile doing, back to its original colours etc?

All i know is that a french chap bought the body/chassis in order to re-use the body tub from it to repair his racer.
Someone has at some point attempted to convert it to two seater by adding a roll hoop, harness mounts and seat bars.
I cannot see any identifying marks on it, are they hidden or just not there?
Any help much appreciated.
Thanks, Phil.
