Well I've failed to get through them all again within the hour!
TigerTabby and CooperNicola, thank you for responding, it was my pleasure and I hope the answers prove fruitful for you in any further research. I hope the archives trip goes well for you as well Nicola, I always love going down there, it's a shame I don't get to do it that often.
I can't say for certain when I'll next be back in to answer the remaining questions. While I'd love to spend all day looking at photographs the bosses would not best pleased.
If you are desperate for an answer I do urge you to check out Forces War Records' Photo Expert available here: https://www.forces-war-records.co.uk/photo-expert
Several other researchers will be on hand in the Photo Expert section to answer any queries.
All the best.
