Hi Len,Reg Neal, When i was at the factory, the Foreman was Albert Wadley other names i recall, Arthur Eke, Dorrington, the Timmins brothers, "Sailor" Brown, Bluck & Stagg, i had left before 1947. Len.
Could the Dorrington you remember have been Fred? He was my paternal grandfather. I'm sure I was told that he was awarded an MBE or suchlike for 40-something years at the PO factory but I don't know where it was. He died aged 96 sometime in the mid-1970s so he would have retired in the 1940s. His wife was Ethel and they lived in Woodwells Rd (Alum Rock) for many years.
