I'm going to be posting my progress here so it's all in one place.
So, as previously posted, my new project, a Seneca Improved View 8x10, variant 4, arrived last week:

This is going to be kind of a long-term project, as there's plenty going on without trying to spend hours in the garage. So just for kicks this weekend, I pulled the handle retainers and soaked in Tarn-X to see what the finish looks like:

Not bad, some brassing shows through, but definitely an improvement. First thing's first though - have to pull the bellows. I manage to pull all the screws in the back, but the front ones are harder to get to. In trying to manipulate the folds to fit a screwdriver in, it became obvious that the first folds are in rough shape. I'd hoped these bellows would be workable for while at least; now I'm not so sure. Have plenty of gaffer's tape, I'm going to try to piece it together (no holes that I can find), but I've already spoken with Sandeha about a new set. An eventuality, but I'd rather make that later than sooner.
Anyway, the bellows are out:

Stay tuned.
