Just this one at the moment. The Austin and Morris bonnet is fronted by a box section, which will rust - see the n/s end of this bonnet. The Wolseley is double skinned right at the front, but isn't a box section and seems to survive quite well.
Typical door rust - bottom of the door skin disintegrating. The door bottoms suffer as well. First one is rather extreme. Make sure that the drain slots are open and that you fill the door bottoms with some form of rust preventative.
I haven't got much for this section - you are invited to add some good horrible stuff if you can!
