You got me wondering with this post, 1987. I have an old wheel down in the dungeon, a No Record stamp Record hub laced to a Nisi rim. I have two splined tools and they both fit over the old locknut, but one just barely. One tool , which as I remember is a Phil Wood tool, fit over the locknut quite easily. But I see what you mean about the older locknuts having a slightly wider diameter. I never tried this before because the bike/hub came with a two prong Caimi FW on it.
