I can see now the bottom of the seat tube is full of mud and dirt which is wet and seems to have caused it to rust from the inside out. I think this is down to no drain holes but it’s had a Thomson seat post (no holes) on it all its life though so I’m not sure where it’s got in… I can only think of the brake bridge.
