I have a winchester commemorative edition but it isn't a pre-64. Mine is a 1967 Canadian Cential w/ a 26" hexagonal barrell. It is in 90% condition and is an accurate and fun shooter.
One is for sale on gunbroker with the box for $450 but I will take $300 for mine. I have had it for over 20 years and actually love the rifle. I want to build an AR10 so I need the funds.
