I spent a bit more time with sandpaper and scraper the other day. Here's what things look like on the seat tube at the moment. It seems the joint for the right side seat stay is also a bit sketchy. I wonder if the joints were ever in great shape. I'm not able to get a very good picture in my somewhat dim basement shop, and it's too dang cold to take it outside for better pictures right now.
