Geoff, of Uppingham Road, can add some more information about Len.
He says: "Len lived in the Newbridge Street area of Leicester in the 1930s.
"When the war broke out in 1939, there was a factory in Walnut Street called Spires, which was taken over by Armstrong Siddeley's and went on war work.
"Len got a job there as a labourer and worked until the end of the war."
While there, he got to know Alec Hibberd, Geoff's father. Geoff and his brother Keith were interested in boxing, having done a little bit at school. Geoff had joined Caldecote Road School Youth Centre in 1943, and Keith in 1945. Alec Hibberd wrote to the Leicester Education Committee and managed to get Len an evening job of training some of the lads at the youth centre in the art of boxing, with some success, and he was there for two and a half years from 1944 to 1946.
Geoff says: "When the war ended Len started his own career again, as mentioned in your story. After he had retired from the ring in 1947 he got a job at Bentleys in Newbridge Street, in the packing department, and moved down to Parker Drive, when the knitting and fitting sections moved there in 1949.
