I think this is the reconstruction of chassis no. 026 that was all but destroyed in a fire in practice at the Nurburgring in 1967.
The remains were bought by Ferrari collector Pierre Bardinon and eventually sold 16 years later to Corrado Cupellini.
He reconstructed the car but it is unknown how many of the original components remained in this recreation.
Of course, I may be wrong but all the details appear correct.
