- ‘Both Wilson and his gunsmith, Larry Cooper, consulted with John Linebaugh, then had Cliff LaBounty rebore and Dave Adams rechamber the gun to another calibre.’
- ‘You had to rebush the rod if the slack was excessive, or rebore the big end if it was split - all of which you hoped could be deferred until the entire affair had to be dismantled for white-lead testing.’
- ‘This makes it possible to rebore bushings which have been used on the left side and reapply them on the right side, thus prolonging the life of the bearings.’
