Here is a pic of the barrel code, and the serial number (minus the last two digits)

What confuses me is that there are 4 letters, instead of two, right? Then I read somewhere that if the factory does work on it, it gets another set of date stamps.
Of course, I am probably wrong!
But reading right to left
Manufactured April 1966
Repaired? July 1971

It also has the 20 inch barrel.

Don't matter much how much it is worth. Good to know that is money well spent. Most guns are smile
I have a 7 and soon to be 5 year old in line to use it.
I'm thinking for now I will get dual dovetail Leupold mounts and rings, and set my 2.5-8X Leupold on it. Maybe a mild bedding job.
