A good time to ask as I'm researching P basses too! I know you've had a 62RI with a 42mm nut. I have one here that might go for the chop.
I see the '63 & '58 P's are as you say, 7.25 on 44mm. The two basses on my radar are: Steve Harris P. 7.25" 41mm and the Mike Dirnt 9.5" at 40mm. The only thing is that both of these have fat necks that you might not like but I love the idea despite not having tried them myself!
Oh wait! 70's P basses. The Nate Mendel is a 7.25 with a 40mm nut. - it's apparently based on his own 71 (??) P bass. - I'm also wondering if my rather awesome 'law-suit' is the same spec, but have to say, is a better bass than the Nate I played recently!
[/quote]Having played a Harris sig bass and a Dirnt sig bass I much preferred the Mike Dirnt as it was much lighter and felt nicer to play I am a huge Arry fan but did not really like the bass as much as I thought I would by the way there is a new Harris sig bass on ebay for £848 http://www.ebay.co.uk/itm/Steve-Harris-Fender-Precision-Immaculate-Bass-Iron-Maiden-REDUCED-BARGAIN-/232064140523?hash=item360819c4eb:g:c-sAAOSwFe5XxFLp buy it now which looks a good buy to me
