I could have bought one of these in about the same condition for $20.00 today. The hook was complete and operational. I really didn't know enough about them to commit, so I passed. Thought?
I just checked eBay as that is usually a great price guide as not much slips by under the radar in great deals. I would say it is worth $15 .... Their are plenty on eBay, but they are not selling for $20-$35.... I would say $15 would of been a fair price if it was all intact and in a okay condition.
