Mid-late 80’s Sugino or Sugino copy, allows you to adjust the chainline 1-2mm. Loosen the lockring (perhaps with your ancient RockRing tool) and then use the pin wrench to adjust the cups. Then tighten the lockrings. Takes a little practice but works well, and the sealed bearings generally lasted a long time.

Recently purchased a new one, NOS, Performance brand, 115mm spindle.
