Hi Mike ,
I hope Santa brought you wanted and I wish you a happy and prosperous New Year to come. In regards to TID's , I do not know what photo's you have, but if you go to to this site "riverman.gotdns.com/gallery/index/php. There are three good and informative photos on No's 3, 52 and 172. 52 is close up in colour in Portsmouth, but not under PAS or CD tugs colours, also 3 looks as she was brand new under the RN.
All the best,
David
