Just to frame this deal for the op, I looked at one three weeks ago that looked like something the cat dragged in.

$425 was the asking. I am still looking. Robbie found one for me as well, but I had just purchased a frame from a friend. Couldn't move that quickly.

I was looking at your pics pretty closely today. That bike has about two hours of work and she'd be ready for a very long ride.

I'd do a saddle, bar tape, tires, brake pads, and a general lube. Maybe new chain/cables as well, depending on wear.

For the 700 miler "I" am doing this summer, I have Surly racks and Berthoud fenders I'd use as well.

Have fun with her, you'll have some great adventures.
