The Houghton le Spring CLB Company, company number 1686, originally opened in 1900. The 1913 Brigade List indicates that the company had shut down. The photograph shows that it had been re-established. From the collar badges I would date the picture as late 1920s, early 1930s. The lads are at camp, and as the CLB had large area camps, I would guess they were at the North Eastern camp. At one time the Durham Diocese had many CLB companies (60+), today there a handful. Nice photo.
