If you are buying for nostalgia or if you are buying it to use would make a difference. It's roughly 50 years old. If you are bidding because its old and quirky, that is one thing. If you want a blade to use, I think you can do better. I would do some measuring on the 3 pt to see if you can even use it on a modern one series. As stated in the post above, you can buy a new one for not a lot of money that you know will work great.
