Unfortunately the Momo wheel and ZF box are gone......
What is your opinion of the Petri wheel, Csl or after market wrap?
At first glance it looks to me like an aftermarket wrap in Napa leather. The part that makes it tricky for me is this. Firstly, there are numerous purportedly genuine CSL petri wheels that don’t have the stitching on the spoke ends. Particularly on UK wheels. Secondly, the stitching does look correct along the rim. However, the CSL “euro stitch” is also the “easiest” for aftermarket shops to reproduce. It is the defacto stitch on even the poorest recovers that one sees.
My honest opinion is that given that this is an LHD car and there is no stitching on the spoke ends, plus the new grey-ish color of the leather, I would say it was a well executed recover.
Steering wheel fanatics will get goosebumps when they see nice leather patina on a steering wheel. The same way a coin collector likes to see no evidence of polishing on uncirculated coins. I personally have no concern with recovered or restored wheels for those that need it. The wheel is rare enough that finding a core is difficult, and restoring one is par for the course.
My thoughts differ on momo wheels. The stitch is hard to reproduce and done poorly 90% of the time. Few momo wheels are truly rare, so I would much rather see an unmolested original over a spruced up one or a recover.
