Ron, while coals may now be brought into the Tyne, sawn timber was not exported from Blyth.
As mentioned, despite the funnel if it's pre-1910 then she seems to be the 1888 vessel.
Actually my eye was drawn to the tier of 3 steamers astern and particularly the outside one seems to be in the colours of the Dannebrog company. Looks like a low if any fo'csle and a long quarterdeck extending from bridge to stern. Also small and old enough to carrry the gaffs on her masts. Photo comparisons from the WSS book on Dannebrog published back in 1973 suggest to me STJERNEBORG of 1899-1906 as one candidate, built by Richardson, Duck in 1888 as ROSARIO, but there could be other possibilities, but she would fit the period.
