Lithgow No1 mk III* nose piece fitting?

[HOOKED ON HISTORY]

First, get the top of the forearm true. This takes a long-sole (10"+) plane set for the smallest cut possible - about .001" - operated by someone who knows how to sharpen, adjust, and use it. Lacking that, use a long hardwood sanding block with finest-grit garnet paper. Once done, rub soft artist-grade white chalk on the true surface and leave the handguard bare. Press and rub together in position, then use a very sharp cabinet scraper to work down the high spots where chalk has transferred. Repeat until chalk indicates full contact. (Same process as fitting the bass bar on a violin. See Derek Roberts Violins - Fitting the Bass Bar for photo tutorial.)

Excellent! I knew there was a trick. The fitting is presently acceptable but I tend to be a bit of a perfectonist to the degree possiable. I must also decide if I should replace the butstock with fresh wood.Coachwood buttstocks are avaliable NOS at a very reasonable price. Any opinions on if I should replace the buttstock? The original is not in bad shape but contrasts greatly with the new forend & handguard. The forend also has the wartime profile (rather large) as opposed to the current butt whis is quite slim at the wrist.
