At least for me it is. I reeled in a excellent example of the Python 2-1/2" yesterday. It is from the first year of production for that barrel length 1963. And to quote the seller " fit,finish, and workmanship is outstanding". I decided I had waited long enough to grab one and they certainly are not getting any cheaper. Most now seem to start at around 1800 and go up from there. To get one of the 1963 models was just icing on a very sweet cake! Sorry about the pictures but its all I have at the moment. I promise more later. Enjoy!
