The second one, the natural, belonged to a friend of mine, who imported it from the USA in 2009 and only sold it in 2023 to the actual seller...
It was already refinished in white when he received it, but it wasn't a great job when looking close, so a local luthier (Olivier Roux from Saint-Nazaire) turned it into a natural finish, but everything else is fully original, except the frets that were dead in 2018, so another luthier (Cyril Guerin) turned it into fretless and it was refretted just before its sale in 2023 by the same person, and it even comes with its original case.
Maybe worth asking @BassAgent.
If French is a problem, just ask, and I'll help you.
