Thanks, C-R!
As I've told Seamus, the 825 is particularly nostalgic for my mum and grandparents because they had one as their first-ever cleaner. It was in faithful service from 1936, when they bought it until sometime in the 70's when they replaced it with a Junior 1346A, which must have seemed incredibly small in comparison! My granny can't remember what happened to the 825 when they replaced it...it was still working, and she things she gave it away to a friend, so who knows - could still be out there, tucked away in the back of someone's garage!
