After much butchery and practice on cheap beaters, I was able to pass off a decent refurbished pipe. I tried to make them look better than new. This included extensive modifications and altering of the shape in some cases. If I sold a pipe I was always honest about the repairs made.
For a while now I try to make them look factory original. Original proportions, color, and finish. I prefer mild patina on classic Brit wood.
The restoration on the Sasieni is remarkable, on the Grabow too for that matter. For me, the only old pipes I have are my own or my father's. I wouldn't touch either (other than some reaming of the bowl) for sentimental reasons. If I bought a restored pipe, I'd still want to see the dings and signs that the pipe had lived a lifetime before it came to me. Perhaps that is just my sentimentality. I'd feel like I was sharing something with someone long gone.
