I will throw my hat into the ring on this one because I have learned a really different outlook on this subject.
As most vintage bike collectors know, you will often end up with bikes like this in group-buys or just end up with them given to you and at the end of the day they arent worth dealing with in alot of situations.
I realized after years of doing this, that there are actually a decent amount of young girls and ladies who are into restoring and riding vintage bikes and just cant jump right in with a Phantom or an Elgin or something of that nature. I started posting them for real cheap, like 50-75 bucks and I was surprised to sell all of them to 18-30 year old women who were actually going to rebuild and ride them.
So....having said that, instead of letting to go back into the earth, maybe pass this one to a girl to build as her own starter bike and stoke the flames of passion in someone else.
