Pilot of high performance tail wheel aircraft landing Runway 35 UAO reports near collision with C150 taking off on Runway 17.

Narrative

Airport active runway was 35 (calm wind runway for UAO). I monitored ASOS for 1 minute. Weather was clear below 12 degrees; plus 6 visibility; calm wind. I was monitoring CTAF for UAO and report 6 southwest for a 45 entry for 35 in 2 minutes. C150 report downwind 17 UAO. I advised C150 UAO using 35 for calm wind. Pilot (with broken English) advised he would land (17) clear runway and taxi (Taxiway A) for 35. I advised copy. I noted the Cessna land and clear runway to Taxiway A at A3. I continued visual approach with a 180 degree (slip in) to final (normal for [my] tail wheel aircraft.) No aircraft on runway or final or base Runway (17) normal approach and touchdown. As I was rolling to a stop; a C150 passed left wing of me at approximately 10 FT southbound or Runway 17. I cleared at A2. Noted C150 climb out southbound. I requested; 'what flight school are you from?' In very broken English reported departing southbound. A single engine turbo-prop reported seeing the C150 climbing out from departure on Runway 17 UAO; and took evasive action. C150 reported turning west bound again in very broken English. My best guess is the C150 was a second aircraft using 17 and was not communicating through UNICOM/CTAF. A local flight school from a nearby airport sends lots of their students to UAO on student solos. I located the flight school and they did identify the student as theirs. They assured me he would be receiving additional training prior to any solo flight. UAO will have a tower under construction in November. I can't wait!
