The Vox Clubman didn't change too much over the years, and this parts list, printed by the Thomas Organ Company and issued to American dealers in March 1966, covers models made across the period of production, 1962-1967. although few were imported into America initially. The Clubman bass was only built in the United Kingdom, and instruments sold in other countries were all imported from Britain.
This parts list mentions two different control knobs for the Clubman bass, the white plastic knobs that were the standard in the UK, and the knurled metal knobs (part 09-141-0, as opposed to the more widely used 09-314-0) that were not usually reserved for higher end guitars. These metal knobs were, it seems, fitted to most Clubman basses exported to America at least by the mid-1960s.
