Thanks for the very useful info folks.

From the photos I think I can see that the rifle is an FN "commercial post war" action, which fits with the info you have provided. I did find a photo of a similar (complete) rifle on the www, for your enlightenment: http://widforss.chiaro.mrfriday.com/auktioner/bilder/47/V08_242.jpg - I hope the stock layout on mine is better!
