Hubert,
Check the thread pitch. It could be Raleigh standard, which is 1" diameter, but 26 tpi rather than 24 tpi, so an English headset starts but stops after a few turns.
Not sure why there would be a Raleigh headset on a Swedish bike though.

Hi All, I am working on a customers Crescent bicycle (the swedish kind) and it has headset that I can't figure out the standard on. It has no flats for wrenches only three little holes for some kind of specialty spanner. I have tried threading on english, italian and french headsets. The english and italian start but stop after a few threads. The headset will start on an english fork but then stop. Any one know what the standard is on one of these things or have an extra one lying around. I though to chase the threads but don't want to risk it until we are absolutely sure. Thanks.
