Good Morning Mike
To the best of my knowledge all of the Royal Navy TIDs had open bridges and were painted grey / black they were used for general harbour / dock duties including moving the parts of the Mulberry harbours around the country and across the channel to France.
The fate of the tugs that went straight to Finland is unclear and they could have been fitted with covered bridges.
As far as I know the Royal Naval tugs were not armed but I have seen a photo of a TID in dazzle camouflage with what looks like a 12 pounder mounted on a platform over the bow steam winch this photo also showed anti aircraft guns mounted either side of the funnel.
I believe this particular TID to be one of those issued to Finland and I am trying to discover which one it was through contacts in Finland but I don’t hold out much hope of getting to the bottom of the mystery.
Meanwhile I have started the construction of a 6ft version of this particular tug.
Find below a photo of a TID in British service during the war
