Three Brothers - Update

An anonymous (...) tip-off from Twitter sent me to this site, where there's an interesting clue as to where exactly these three boys might have been staying.

South Shore is also a part of Blackpool, and the Brighton was the name of a hotel at 465 South Promenade. The Colonial Hotel, as it is now known, had a bit of a wobble a few years ago when it was fined for hygiene concerns, however it has since been renovated and there are some glowing reviews around on the internet. The hotel is situated directly in South Shore, and although I cannot find when the building dates from (anyone know?? ) it certainly looks as if it could be contemporary to the photographs. I think the first mystery is absolutely solved! :) But then... who is this mysterious C W he was with...? Until I find out...
