i was able to identify and contact the person who posted the last image and got this friendly reply (edited for privacy).
The photo is one from my fathers archive. Unfortunately he passed away in 2013. My Dad at this time was PC xxx xxxx xxxx (West Yorkshire Police)
and is the officer on the left. I am sorry I do not know who the other police officer is but I would think he is now retired. The vehicle may have been used as a motorway patrol car on the M1/M62 in the Leeds area and probably based at the Wooley Edge Police Post on the M1. As that was my fathers post around that time.
Next stop: inquire at West Yorkshire Police. Maybe a shiter has contacts there?
