Now I have had a second cuppa, I have got the other two pics out. As you can see, they are again group pics taken in front of the Chapel which has not changed today. St John's had no record of the Ruddington section. So I sent them the images. Sadly they never updated their website to reflect this.
My Dad recalls the ambulance being blessed.
One pic (the better one) does show the actual bottle just. See the chap 2nd from the left. My Grandad is 5th from the right.
