Dear all, > > >Is anyone here familiar with this file? I'm getting dizzy from going round in circles trying to establish the correct piece, out of 618 pieces, on which to request a quote to get details of a specific change of ownership. > > >The vessel is the snow BRITANNIA, built Biddeford 1810, 189 tons and 41/94ths,  engaged in the Newcastle-London coal trade. > > >In 1825 she was # 129 in the register of the port of London. She had three masters that year. I believe that the third master bought her late in 1825 or very early in 1826. (Certainly she was owned by that master and his Shields associates by 1827.) In 1826 she was #160 (or possibly #168 - the last digit is very faint) on the registry of the port of Newcastle. > > >Where should I look for the transaction - London or Newcastle? > > > >The problem is that the sub-series "London Coasting" goes up to 1820 only. > > >There is a sub-series called "Northern Ports" and in it BT 107/146 is Ports "N" for 1825, but there is not a listing for 1826. > > >The sub-series "England and Wales" does cover 1826 and in it BT 107/185 is Ports I-L and BT 107/186 is Ports M-N. > > > >None of the other sub-series appear to be appropriate. > > >Can anyone help? > > >Regards, >Adi
