Evening all!

Firstly I am new here so my apologies if I am posting this in the wrong place, still getting the hang of things.
I'm wondering if anyone has any advice on finding a past business or trade?
I recently got hold of the correct 1901 census for my great great grandfather which confirmed partly what I already knew but in a bit more detail.
His name was Henry Munday, 33 years old in 1901 - occupation was 'confectionist / tobacconist' - his 'own account' and the workplace is recorded as 'at home'. Home for them was 67 Raynham Road, Upper Edmonton, Middlesex.
I can only imagine by the information given is that address was the address of the shop and the family lived above it as many did. If not, it surely wasn't far away.
By the time the 1911 census comes around he is an 'oil cloth worker' (again, confirming a story of him being a notorious gambler and probably losing the business).
Back to the point, I'd love to know if I can find out any more information. The name of the store, the exact location or the holy grail - a photograph. (Or even what happened to him after 1911).
It doesn't seem like that exact address is there anymore and a quick search of WW2 bomb sites during the blitz shows a drop courtesy of the Luftwaffe right about where it's roof would have been!

Regardless, if anyone could help or offer anymore advice it would be hugely appreciated!
Thanks for reading

Joel.
