The pin at the start of Farewell to Arms is extremely corroded and I was nearly able to get it out pulling hard with a shoulder length sling last week. I'm not sure it will come out without falling apart (leaving no space for a replacement), I do that it is unlikely to hold a falling climber. I'm hoping to get some time this week to have a go at it, yank the mank and replace. If somebody beats me to it, that'd be good too.
