I am trying to find photos and history of the paddler ERIN's ISLE, built for the Belfast & County Down Railway.
Can anybody help?

this is the only one I can find at the moment....

Hi Mick
many thanks for the image. It looks like it was taken at Bangor pier, having brought passengers from Belfast. Date must be 1912 to c.1915.
I believe she was sunk in WW1 as a minesweeper, and never replaced. Steve

there's a little bit about this ship in 'Paddle Steamers' by bernard cox....
...On the 12th june, 1912, the Scotish shipbuilding yard of A & J Ingliss launched the Erins Isle, a fine steamer with her promenade deck extending the full length of her hull. She was the first vessel of this type owned by the Belfast & County Down Railway Company.
