Help for Louise

Hi guys it’s a long shot but I’m looking for my grandad I have a very limited amount I know about him. His name is Sidney William Nicholls he lived at 23 Hyde street deptford in 1963&64 he lived with his dad who I believe is Sidney Nicholls (He was a lorry driver) & younger brother. I believe he would now be around 80 He was in to motorbikes and tattoos other than that I don’t know much 🙁
