Graeme Perry reported that:-
"These works were run by William Culley until his death on 10 August 1905. He was buried in Great Barton churchyard. His son, also named William, who had frequently gone to the works in his spare time to help his father, took over, presumably giving up his previous trade as a butcher — he had a shop in Kings Road in Bury St Edmunds — to do so. William Culley jnr carried on the works until 1926, when the management was taken over by Fred Stiff and he continued until 1939, when war broke out.
The original kiln at the Rougham Estate Brickworks was a rectangular Suffolk kiln with a capacity of 30,000 bricks, but this was sited opposite a house owned by a Mr Geoffrey Bennett, who had moved there from Rougham Hall.
Smoke from the kiln was the subject of a complaint by Mr Bennett, and eventually the kiln was demolished and a new, beehive-shaped one, with a capacity of 35,000 bricks was built about 50 yards away from where the old one had been. The remains of the old original kiln could still be seen in 1990.
The works produced a red brick and standard specials of good quality, the bulk of the output being used on the Rougham Estate, but a proportion was sold to local farmers and to builders merchants in Bury St Edmunds.
In the early 1930s the two brickmakers employed made 900 to 1000 bricks a day, working very long hours and for this they were paid 10s. 0d. per 1000 (10 shillings is 50p. today).
