It looks like Musikraft no longer offer full laquer finishes, only oil or a thin sealer. This is the ONE thing I'm not equipped to do, even if decided to build the neck myself. I can do a spray can finish in a rather dusty workshop with less than ideal ventilation. I have done it before on a couple of occasions, and it turned out surprisingly nice, but not like a professional factory finish, which is what I want from this neck.
If I want a finished Musikraft neck I would have to wait months for delivery and then ship it somewhere else (probably out of the country) for the finish. In my location this means a lot of customs paperwork. I'm outside the US, and outside the EU too. That's too much hassle, unless I can't find a better option. My only option locally for a professional finish would be auto repair shops, but I tried that once, and the result wasn't quite as nice as I had hoped for.
Musikraft's Fender Custom Shop neck profiles look interesting, but the one that looks like my best option (60s oval C) is only .79" at the 1st fret, which is the same as the Warmoth slim profile that I don't like. The Musikraft 60s neck does look slightly more "rounded" though, and also gets significantly thicker than the Warmoth higher up the neck so I guess it might work. I love the 1.600" nut width option. That's more or less the same as my BB, and for me that's the perfect sweetspot between a "modern" Fender P-bass and a J-bass. But no finish.... that's probably a dealbreaker for me.
I know I said I'm not picky about neck profiles/widths

, but if I order an expensive custom made neck to replace a neck that didn't feel right, I want it to be perfect.
USACG isn't an option unfortunately. I want a rosewood fretboard and they won't ship rosewood necks outside the US. I though this wasn't a problem anymore, after the exceptions for musical instruments&parts were implemented in the CITES appendix...??? Everyone else seem to be shipping rosewood necks/instruments internationally without any additional customs paperwork or export/import licenses.
WD necks are not an option, the ones I've tried were extremely poor quality, and also extremely chunky.
Allparts MIJ necks look interesting, but they only have one rosewood P-bass neck. It has a compound 7.25"-10" fretboard, which isn't what I want, and also .092" at the 1st fret, which is too chunky for my idea of a perfect neck.
At this point my best options seems are probably to either build a neck myself (which I really don't want to) and ship it somewhere for a professional laquer finish, or to accept a 38 mm nut width and get a Warmoth standard profile J-bass neck. I like the Warmoth "standard" J-bass neck, but ideally I want a nut width around 40-41 mm (and a 9.5"-10" radius) for this particular bass. Basically something that sits somethere between a Fender AmPro and a Yamaha BBP34. Most available replacement necks with "modern" P-bass nut widths seem to be either considerably more chunky, or too slim front-to-back.
