We present observations of the FR I radiogalaxy 3C 66B made during a joint EVN + MERLIN VLBI session in May 1995. The jet is mapped from the 5 mas scale up to about 3 arcmin. The newly mapped VLBI jet shows essentially two elongated blobs in the direction of the brightest kpc jet (NE). We also present the first results obtained for a two-fluid model for VLBI jets.
