Here is my 2c
Depends what your doing with it...
Pre-War rifles didn't have the good scope mounting system. If you want to shoot open sites, utilize the old scope mounts, or build a custom rifle, then these rifles are defiantly top of the list cool.
The Post war, pre-64 guns are very very good rifles and maintain the cool factor with all the modern scope mounting possibilities without customizing (or drilling holes) in a vintage gun.
The post-64 push feed guns are bottom of desirable list. But these can be very good guns if you are not concerned with CRF action and the pre-64 cool factor.. They are relatively easy to get parts for compared to the older guns. I personally have one of these customized, Its an excellent gun for what I using for, and it didn't cost first born son.
The new CRF riles are excellent and arguably perhaps function better than the pre-64 guns at about 1/2 the price.
At the end of the day, its all about what your going to do with it, how much you have to spend, and how much cool factor you want.
