After a long delay I have just posted Bryan Elson's 1952 RL photo into the photo system. Bryan originally scanned this for us late in 2015 and I have apologised to him for the delay.
It's a semi-formal Rugby League group from the 51-2 season in which the school was particularly successful, taking all the town trophies. I would guess that this is an under 14's group. The ball is marked Greenhill GS C League 1951-52. The lower part of the shield is completely burned out but the first two lines are definitely O S R L 'C' League. There appears to be two other trophies, one on each side of the shield.
It was the last season that the school played RL before changing to RU and then soccer, but the success was later celebrated by including a Rugby League Squad in the formal 1954 series of photographs.
The back of this photo has a faded stamp probably Jack Abrahams - Photographer - 146 Yorkshire St - Oldham - Tel. MAIN 3305
Bryan has provided most of the names in the photo and good hints at the remainder. I have taken it upon myself though to name Philip Schofield at 1-04 but I would be happy to be corrected if wrong.
