When did Stockton receive their Tridents?

Just that I'm going to go through my photos to see if I need any for photos, and rather find a point when they arrive rather then trawl through loads of photos.

17025/6 arrived on the evening of the 11th April 2013, and entered service on 7th May.
17027/32 arrived around about the 1st May 2013. 17027 entered service on 3rd June, with 17032 entering service on the 10th both after repaints.
17028/9 arrived on the evening of the 10th November 2013. 17028 entered service on the 13th November and 17029 on the 15th.
