Old Photos of Walworth Road & London Road

Not sure if anyone can help I'm trying to track down some old photos of the CP Hart & Sons Builders Merchants/Bathrooms shops that were based on Walworth Road & also London Road. Run by John & Tom Hart.

I did find some along time back via the facebook group called Now and Then Walworth. But since then I've not found any other photos.

Any help would be greatly recived!

Have you tried the Southwark Local History Library, in the John Harvard library building, Borough High Street?

They usually have everything you are looking for and are very helpful.

Best of luck!
