Some help with this carrier.

[Nigel Watson]

Hi
I am trying to see if this carrier photo is likely to have been taken during Operation Epsom in Normandy between 26th and 28th of June 1944. The commander of the lead carrier resembles my wife's uncle who was killed on 28th June. The photo has been accredited to not only Epsom but also a later Operation, Bluecoat I think.
Lt. Loudon commanded the Support Platoon which leads me onto my next question. I know the Bridge Plate on carriers can be 3, 4 or 5 and sometimes it was seen on the mudguards, lower front armour and upper front armour in front of driver. In the photo is the marking on the mudguard a 5 for the Bridging Plate or is it an S with a line through it for Support Coy?
