Almost certainly Belgian. The Netherlands were inundated with Belgian frames during the seventies and eighties. Most were delivered to local bike shops fully painted but without serial numbers or decals, after which said shops branded them as their own. Some added their own serial number, but most did not.
That a previous owner chose the Raleigh name is not very surprising, as the Dutch TI Raleigh team was very successful during that era, including a Tour de France win in 1980.
Finding out who built the the frame may prove to be difficult. Most bike shops bought these frames from a wholesaler, and I've found that they often knew little more than that they were "Belgian factory frames". The builders couldn't tell, obviously.
Two companies that were certainly capable of producing high quality racing frames in significant numbers were Martens and Vaneenooghe.
What brand are the dropouts and fork ends?
