<a href="http://www.tiltonequipment.com/">Tilton inc</a>., based in Rye, NH has the import and distribution rights to Olympyk (now called EFCO...seems the national olympic commitee had a problem concernic trademarks). Tilton also distributes Jonsered chain saws, which seem to have a fairly strong market presence in some parts of Wi; anybody with a Jonsered sign should at least know how to get parts.
Tilton told me they no longer distribute Olympyk, Olympic, Oleo Mac, or Efco whichever name you care to use. I was told they are distributed from an outfit in Ohio. Nobody ever "bought out" Olympic, they have changed their name depending on which country they sell in . Here in the US they are Efco, in other countries Oleo Mac, all the same fine high quality product. There are Efco dealers all over the place. You can easily find an Efco dealer by searching on Ebay
